In a recent court case, it was found that during a period of 11 years 896 people were selected forgrand jury duty and 35% of them were from the same ethnicity. Among the people eligible forgrand jury duty, 79.8% were of this ethnicity. Use a 0.05 significance level to test the claim that theselection process is biased against allowing this ethnicity to sit on the grand jury. Identify the nullhypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, andfinal conclusion that addresses the original claim. Use the P-value method and the normaldistribution as an approximation to the binomial distribution.Which of the following is the hypothesis test to be conducted?Ho: P0.798(choose a for = ; b for > ; c for < and d for +)H1: p0.798(choose a for = ;b for > ; c for < and d for 7)What is the test statistic?Z =(Round to two decimal places)What is the P value?(Round to three decimal places.)What is the conclusion on the null hypothesis?(Reject or Do not reject)

Given data sample size, n =896 population proportion,p= 0.798 Significance level,…

.2.3 Assigned Media The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) a = 0.01, (b) a = 0.05, and (c) a= 0.10. P=0.0618 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? A. Reject Ho because the P-value, 0.0618, is greater than a= 0.01. B. Reject Ho because the P-value, 0.0618, is less than a =0.01. C. Fail to reject Ho because the P-value, 0.0618, is less than oa= 0.01. O D. Fail to reject Ho because the P-value, 0.0618, is greater than a= 0.01.

While her husband spent 2½ hours picking out new speakers, a statistician decided to determine whether the percent of men who enjoy shopping for electronic equipment is higher than the percent of women who enjoy shopping for electronic equipment. The population was Saturday afternoon shoppers. Out of 68 men, 24 said they enjoyed the activity. Eight of the 23 women surveyed claimed to enjoy the activity. Interpret the results of the survey. Conduct a hypothesis test at the 5% level. Let the subscript m= men and w= women. What is the test statistic? (If using the distribution round your answer to two decimal places, and if using the t distribution round your answer to three decimal places.) What is the p-value? (Round your answer to four decimal places.) Sketch a picture of this situation. Label and scale the horizontal axis and shade the region(s) corresponding to the p-value. i. ii. iii.
