A sample of n = 12 data values randomly collected from a normally distributed population has variance s = 17.2. We wish to test the null hypothesis Ho:02 = 9.9 against the alternative hypothesis H1:0? > 9.9 at a significance of a = 0.05. What is the value of the test statistic? Write your answer rounded to 3 decimal places. What is the critical value? Write your answer rounded to 3 decimal places. Do we reject the null hypothesis? Owe fail to reject the null hypothesis. OWe reject the null hypothesis.
