Question
Use a x²-test to test the claim o² = 0.47 at the x = 0.10 significance level using sample statistics s² = 0.479 and n =21. Assume the population is normally distributed.
Identify the null and alternative hypotheses.
A. Ho: o² ≤0.47
H₂: o² >0.47
C. Ho: ² 20.47
H₂:0² <0.47
Identify the standardized test statistic.
(Round to two decimal places as needed.)
Identify the critical value(s).
(Round to two decimal places as needed. Use a comma to separate answers as needed.)
Choose the correct conclusion below.
O B. Ho: o² #0.47
Ha: o² = 0.47
D. H₂: o² = 0.47
H₂: o² #0.47
O A. Reject Ho. There is not enough evidence at the 10% level of significance to reject the claim.
B. Reject Ho. There is enough evidence at the 10% level of significance to reject the claim.
C. Fail to reject Ho. There is not enough evidence at the 10% level of significance to reject the claim.
D. Fail to reject Ho. There is enough evidence at the 10% level of significance to reject the claim.
