6. To test Ho: u = 80 vs Hi: < 80, a simple random sample of size 22 is obtained from a population that is known to be normally distributed. It is given that ΕΎ= 76.9 and s = 8.5. Test this hypothesis at the a = 0.02 level of significance. Step 1: Test statistic: Step 2: Compare the critical value to the test statistic. Step 3: Conclusion
