1. what is the value of the F test statistic for testing the hypothesis that age, on average, has no effect on running time?
2. what is the value of the F test statistic for testing the hypothesis that fitness, on average, has no effect on running time?
3. what is the value of the f test statistic for testing the hypothesis that the effective age, if any, on running time does not depend on the runners fitness?

A comparison between a major sporting goods chain and a specialty runners' store was done to find who had lower prices on running shoes. A sample of 27 different shoes was priced (in dollars) at both stores. To test whether the average difference is greater than zero, the hypotheses are as follows: Null Hypothesis: HD = 0, Alternative Hypothesis: MD > 0. If the average difference between the two stores (specialty - chain) is 0.72 with a standard deviation of...

In the past the average age of employees of a large corporation has been 40 years. Recently, the company has been hiring older individuals. In order to determine whether there has been an increase in the average age of all the employees, a sample of 25 employees was selected. The average age in the sample was 42.5 years with a sample standard deviation of 5 years. Using a significance level of α = .01, do the sample data provide support...
