24. A simple random sample of 40 salaries of NCAA football coaches has a mean of $415,953 and a standard deviation of $350,000. Test the claim that the mean salary of a football coach in the NCAA is less than $500,000.Use a = 0.10. (Be careful when typing these values into your calculator!!! There are lots of zeros!) Would this be a z-distribution or t-distribution? Why State the hypotheses: (in symbols and words) Ho: Ha: State the level of significance: Compute the test statistic: Find the p-value: Choose the correct conclusion: Reject Ho: or Fail to reject Ho: Write a sentence explaining your conclusion in terms of the claim

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
