A sample of 18 items provides a sample standard deviation of 4.9 . Test the following hypotheses using a=0.05. What is your conclusion? Use both the p-value approach and the critical value approach. Find the data for Test statistic= (3rd decimal), P-value low from table (3rd decimal), P-value high from table (3rd decimal),, X^20.05 (3rd decimal), Reject H0 if X2>= (3rd decimal).
