Chat 3 Use the Hypothesis Testing: Procedure for Hypothesis Tests flow chart interactive to answer the following question. In conducting a hypothesis test of the claim that p > 0.4, the critical value is z = 2.33 and the test statistic is 2.88. Which one of the following is the correct decision stated in nontechnical terms? Choose the correct answer below. ( A. There is sufficient evidence to reject the claim that p > 0.4. ( B. There is not sufficient evidence to support the claim that p > 0.4. O C. There is not sufficient evidence to reject the claim that p > 0.4. ( D. There is sufficient evidence to support the claim that p > 0.4. In a recent court case it was found that during a period of 11 years 890 people were selected for grand jury duty and 35% of them were from the same ethnicity. Among the people eligible for grand jury duty. 78.9% were of this ethnicity Use a 0.01 significance level to test the claim that the selection ocees is biased against allowing this ethnicity to the grand jury. Identify the null hypothesis, alt othesis, alternative hypothesis, test statistic, P.value, conclusion out the null hypothesis, and final conclusion that addresses the original claim. Use the P.value method and the normal distribution as an approximation orial distribution. Which of the following is the hypothesis test to be conducted? D A Ho: P= 0.789 O B. Hop0.789 Q D. Ho:p#0.789 H1: p=0.789 H1: p=0.789 OE. Ho: P-0.789 OF. Ho: P-0.789 H1: p* 0.789 H1: p > 0.780 What is the test statistic? (Round to two decimal places as needed.) What is the P.value? P.value - (Round to four decimal places as needed.) What is the conclusion on the null hypothesis? O Fail to reject the null hypothes eater than the significance level, o. Reject the null hypoth cause the P.value is hificance level, a. O Reject the null hypothesis bec equal to the significance level, a. O Fail to reject the null hypothesis because the P-value is le qual to the significance level, a. Does the jury selection system appear to be fair? A. There is not sufficient evidence to warrant rejection of the claim that O B. There is sufficient evidence to support the claim that the selection the selection process is biased against allowing this ethnicity to sit process is biased against allowing this ethnicity to sit on the grand on the grand jury. The jury selection process appears to be fair jury. The jury selection process appears to be unfair. DC. There is sufficient evidence to warrant rejection of the claim that the O D.
