Suppose you want to know if there is a difference in the average high temperatures in February 2019 for three different areas. you record the following temperatures randomly for the three cities.

A	B	C
18	-11	14
23	11	23
39	12	40
8	4	21
-4	-2	12

You decide to run a one-way ANOVA test on this data.

A) write down the null and research hypotheses you are testing

B) What are the F- statistic and P value of your ANOVA test? interpret these numbers (explain).

C) What is the conclusion of your hypothesis test with significance of a=0.1?? Explain this conclusion in the context of this problem

D) If you wanted to compare the average temperatures pairwise, how many hypothesis tests would you have to perform (explain)?

E) It turns out the above daily high temperatures were recorded on the 4th, 8th, 12th, 18th, and 26th respectively of all three cities. Does this information change the test you would run? Explain.

Suppose you want to know the variance of the weights of the only five iguanas in a particular zoo. You measure their weights to be 8.3, 8.4, 8.6, 9.2, and 9.5 pounds (15 points) What was different between the population variance and the sample variance? Which is bigger? Why is there a need to have a different formula? Write at least five good sentences in answering this question. (3 points) The population standard deviation is the square root of the...

A town’s December high temperatures average 46 oF with a standard deviation of 9 oF, while in June the mean height temperature is 75 oF with a standard deviation of 8 oF. In which month is it more unusual to have a high temperature of 64 oF? a. June because the z-score is farther away from zero than for December b. June because the z-score is closer to zero than for December. c. December because the z-score is closer to...
