A sample of n = 15 data values randomly collected from a normally distributed population has standard devlation s = 2. We wish to test the null hypothesis Ho:0 = 1.6 agalnst the alternative hypothesis H1 :0 > 1.6 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 reject the null hypothesis. O we fall to reject the null hypothesis.
