A simple random sample of 40 salaries of NCAA football coaches in the NCAA has a mean of $423,811. The standard deviation of all salaries of NCAA football coaches is $463,364. Test the claim that the mean salary of a football coach in the NCAA is less than $500,000. Use a 0.05 significance level and conduct a full hypothesis test using the six-step process.

The salaries of a random sample of 50 major league baseball players for 2012 are 3.44 million dollars. Assuming the distribution of salaries for all major league baseball players is normally distributed with a standard deviation of $0.712 million, test the claim that the mean salary of major league baseball players is less than 4 million dollars. Use a significance level of 0.05. What is the test statistic? What is the critical value? What is the p-value? What is the...

A report by the NCAA states that 57.6% of football injuries occur during practices. A trainer for a particular team claims that there are significantly less practice injuries in his team’s conference, so he randomly selects 36 reported injuries and finds that 17 occurred during practice. Conduct a hypothesis test to evaluate this claim at the .05 significance level. Be sure to include the following: a) The null and alternative hypotheses. b) The value of the point estimator for the...

A simple random sample of 70 customers is taken from a customer information file and the average age is 36. The population standard deviation σ is unknown. Instead the sample standard deviation s is also calculated from the sample and is found to be 4.5. (6 points) Test the hypothesis that the population mean age is greater than 33 using the critical value approach and a 0.05 level of significance. Test the hypothesis that the population mean age is less...
