Test the claim that for the population of statistics final exams, the mean score is71

71using alternative hypothesis that the mean score is different from71.

71.Sample statistics includen=24,

n=24,x

=72,

x=72,ands=17.

s=17.Use a significance level of?=0.05.

?=0.05.(Assume normally distributed population.)

The test statistic is

The positive critical value is

The negative critical value is

The conclusion is

A.There is not sufficient evidence to reject the claim that the mean score is equal to 71.

B.There is sufficient evidence to reject the claim that the mean score is equal to 71.

(1 point) Test the claim that for the population of statistics final exams, the mean score is 71 using alternative hypothesis that the mean score is different from 71. Sample statistics include n = 24, x = 72, and s = 17. Use a significance level of o = 0.05. (Assume normally distributed population.) The test statistic is The positive critical value is The negative critical value is The conclusion is O A. There is not sufficient evidence to reject the claim that the mean score is equal to 71. O B. There is sufficient evidence to reject the claim that the mean score is equal to 71
