A sample of n = 47 data values randomly collected from a normally distributed population has standard deviation s = 2.3. We wish to test the null hypothesis Ho :0 = 2.8 against the alternative hypothesis H1:0 # 2.8 at a significance of a = 0.05. What is the value of the test statistic? Write your answer rounded to 3 decimal places. What are the critical values? Write your answers rounded to 3 decimal places. Upper CV: Lower CV: Do we reject the null hypothesis? O We fall to reject the null hypothesis. O We reject the null hypothesis.
