A sample size of 35 is used to test H0: m 65 vs. Ha: < 65.
Given that = 63.5 and = 2.5, answer the following questions
What is the computed value of the test statistic?
What distribution does the test statistic have when the null hypothesis is true?
Is the alternative hypothesis one-tailed or two-tailed?
What is the p-value?
Step by step method for testing the hypothesis under 5 step approach is discussed here. Excel template for each problem is also included. This template can be used to obtain the answers of similar problems.
