Question

Use a test to test the claim o? -0.53 at the a0.01 significance level using sample statistics s' =0.483 and Identify the null and alternative hypotheses. 23. Assume the population is normally distributed O A. Ho: 62 -0.53 He: 02 +0.53 OC. He: 220.53 He: 02 <0.53 O B. Ho: 02 +0.53 H,:o? =0.53 OD. Ho: 0250.53 Hy: OP >0.53 Identify the 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 A. Reject Ho. There is not enough evidence at the 1% level of significance to reject the claim. OB. Fail to reject Ho. There is enough evidence at the 1% level of significance to reject the claim. O C. Fal to reject Ho. There is not enough evidence at the 1% level of significance to reject the claim. O D. Reject Hy. There is enough evidence at the 1% level of significance to reject the claim.

Answer 1

The statistical software output for this problem is :

One sample variance summary bypothesis test: O : Variance of population H:0=0.53 H :6=0.53 Hypothesis test results: Variance Sample Var. DF Chi-square Stat P-value o 0.483 22 20.049057 0.8401

Hypothesis : Option A is correct.

Test statistics = 20.05

Critical value = 8.64 , 42.80

Conclusion : Option is correct .
