Suppose the population is normally distributed. Given the sample size of 25, with sample mean 740 and sample standard deviation 80, we carry out the following hypothesis test.
Is this test for population proportion, mean or standard deviation? What distribution should you apply for critical value?
Determine the test statistic? (Show work and round the answer to three decimal places)
Determine the p-value? (Show work and round the answer to two decimal places)
What is your conclusion of the test at ? = 0.10 level? Why? (Show work)
