What patterns do you observe based on the information in add-in 1?The patterns that I observe based on the information in Table 1 ar The level of Dissolved Oxygen consistently increases by an increment of 2 with each subsequent selective information point The Number of Fish Observed seems to quiver with no real consistency (with the exception that after the peak of 15 fish was observed, the next3 info points reflect 10, 12, 13 which was the same of fish that were observed in the exact order precedent to reaching the peak 15. (In short, the pattern 10, 12, 13 seems to have repeated itself.) The level of Dissolved Oxygen does not seem to decrease when the Number of Fish Observed decreas es2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the pee sample and the number of fish observed in the frame of water system.Based on the information provided in the table, I would hypothesize that the number of fish observed has no bearing on the level of oxygen dissolved. This hypothesis would be based on the fact that the dissolved oxygen steadily and consistently increased by an increment of 2 with each progressive selective information point. When the number of fish observed was significantly increased from 3 to 10, the dissolved oxygen level only increased by 2. Conversely, when the number of fish observed significantly decreased from 15 to 10, the dissolved oxygen still maintained that consistent increase of 2.3. What would your observational approach be to test this hypothesis?The proveal approach that I would use to test this hypothesis would be to obtain a 2 freshwater fish tanks, fresh water, fish, an aquarium water level meter and a d issolved oxygen meter. In one tank, I would ensure that the aquarium was filled with a specific tout ensembley determined level of water and measure the level of dissolved oxygen present with no fish. Then I would gradually begin adding fish daily, starting with one fish. Each solar daytime I would ensure that the water level remained the same as it was prior to adding the number one fish and I would continue increasing/decreasing the total number of fish daily. I would also consistently measure the dissolved oxygen levels as I introduced or removed fish to observe the levels.In the second fish tank, I would ensure that the level of freshwater and dissolved oxygen matched the levels of the first fish tank prior to addingany fish. Then, I would add the level best number of fish that I intended to observe in the 1st tank and observe the oxygen level. For the duration of the essay, I would not ensure that the water level remains the same but I would not modify the total fish in th is tank. I would also observe the oxygen levels in the 2nd tank throughout the experiment.4. What are the independent and dependent variables?The independent variable in this experiment would be the total number of fish existence observed, and the dependent variable would be the dissolved oxygen.5. What would be your control?My control in this experiment would be the 2nd fish tank, which I would not fluctuate the total number of observed fish.6. What type of graph would be appropriate for this data set? Why?The most appropriate type of graph to utilize, which would best illustrate the data being compared in this example, would be a line graph. I would use a line graph because it most clearly and efficaciously demonstrates how the two independent data sets are related, as well as how their independent fluctuations in volume affect one another.7. Graph the data from Table 1 Water Quality vs. Fish Population (found at the beginning of this exercise). You may use Excel, then Insert th e graph, or use another brief program. You may also draw it neatly by hand and scan your drawing. If you choose this option, you must insert the scanned jpg image here.pic8. Interpret the data from the graph make in Question 7.The data from the graph supports my hypothesis that the total number of fishobserved does not have any bearing on the level of dissolved oxygen, which steadily increases by a level of two with each data point.Exercise 2 Testable ObservationsDetermine which of the pastime observations (A-J) could lead to a testable hypothesis.For those which are testableWrite a hypothesis and null hypothesisWhat would be your experimental approach?What are the dependent and independent variables?What is your control?How will you collect your data?How will you present your data (charts, graphs, types)?How will you analyze your data?1. When a plant is placed on a window sill, it grows three inches quicker per day than when it is placed on a coffee table in the middle of the liv ing room. TESTABLE Hypothesis The plant will grow at a faster rate per day when it is placed on a window sill as opposed to being placed on a coffee table in the middle of a living room. Null Hypothesis The location of the plant has no bearing on thegrowth rate per day. Experimental Approach I would gather four identical plants, two of which I would I would rotate between the living room and window sill daily, and the other two would remain static in their locations for the entire duration of the experiment. I would treat and care for all plants in an identical manner, ensure that their respective locations remained precisely the same, as well as measure and record the growth of each plant daily. After a fitted period of time had elapsed, I would record the final relevant data in Excel, and insert a line graph with all four plants incorporated into a single chart, which would also demonstrate the growth rate everyplace time.Subsequently, based on the information contained inw ardly the data points, and the line graph comparison, I would draw a final conclusion and present my data to implicated parties in the form of a brief Microsoft PowerPoint presentation. I would include a brief summary of the intent of the experiment, a detailed explanation of the tools and exact bidding in which I used to conduct my tests, and all of the raw data statistics relative to the daily growth rate of all four plants. Dependent unsettled The location of the plants. Independent Variable The growth rate of the plants. Control The 2 static plants.2. The teller at the bank with brown hair and brown eye and is taller than the other tellers. NOT TESTABLE3. When go eats healthy foods and exercises regularly, her blood pressure is 10 points lower than when she does not exercise and eats unhealthy foods. TESTABLE Hypothesis Sallys blood pressure will be lower when she eats healthyfoods and exercises regularly. Null Hypothesis The fact that Sally eats healthy foods and exc ercises regularly will have no effect on Sallys blood pressure. Experimental Approach I would first observe and record, for a sufficient period of time, Sallys eating habits, exercise regimen, and blood pressure, when she is not eating as healthy or exercising as regularly to accurately gauge a reliable average of the range of her blood pressure in this phase of the experiment. Then, I would ensure that Sally was placed on a healthy eating plan, approved by a nutritionist, and prescribe an exercise routine. Sallys eating habits and exercise regimen would again be preserve daily, along with her blood pressure statistics and other relevant information.I would track and record the daily relevant statistics in Excel, and I would also use a line graph to illustrate the comparison of her blood pressure over time under the two different scenarios. Subsequently, based on the information contained within the data points, and the line graph comparison, I would draw final conclusion and pres ent my data to interested parties in the form of a brief Microsoft PowerPoint presentation. I would include a brief summary of the intent of the experiment, a detailed explanation of the tools and exact process in which I used to conduct my tests, and all of the raw data statistics relative to the changes in Sallys blood pressure as well as her diet and exercise habits throughout the experiment process. Dependent Variable Sallys eating and exercise plan. Independent Variable Sallys blood pressure reduction. Control the phase of the experiment when Sallys blood pressure is observed and recorded when she is not eating healthy or exercising regularly.4.
