A sample of n=42n=42 data values randomly collectedfrom a normally distributed population hasvariance s2=21.3s2=21.3. We wish to test the nullhypothesis H0:σ2=38.8H0:σ2=38.8 against the alternativehypothesis H1:σ2≠38.8H1:σ2≠38.8 at a significanceof α=0.01α=0.01.
What is the value of the test statistic? Write your answerrounded to 3 decimal places.
What are the critical values? Write your answers rounded to 3decimal places.Lower CV: Upper CV:
Do we reject the null hypothesis?
