Listed below are the numbers of years that archbishops and monarchs in a certain country lived after their election or coronation. ASsume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Use a 0.05 significance level to test the claim that the mean longevity for archbishops is less than the mean for monarchs after coronation. All measurements are in years. E Click the icon to view the table of longevities of archbishops and monarchs. ...... What are the null and alternative hypotheses? Assume that population 1 consists of the longevity of archbishops and population 2 consists of the longevity of monarchs. A. Ho: H1=H2 O B. Ho: H1 #H2 H1: H1 H2 O C. Ho: H1 SH2 H1: H1> H2 O D. Ho: H1 = H2 H1: H1 # H2 The test statistic is (Round to two decimal places as needed.)

Transcribed Image Text:Listed below are the numbers of years that archbishops and monarchs in a certain country lived after their election or
coronation. Assume that the two samples are independent simple random samples selected from normally distributed
populations. Do not assume that the population standard deviations are equal. Use a 0.05 significance level to test the claim
that the mean longevity for archbishops is less than the mean for monarchs after coronation. All measurements are in years.

What are the null and alternative hypotheses? Assume that population 1 consists of the longevity of archbishops and
population 2 consists of the longevity of monarchs.
A. Ho: H1= H2
H1: H1 <H2
O B. Ho: H1 #H2
H: Hq>H2
O C. Ho: H1SH2
H1:H1> H2
O D. Ho: H1 = H2
H1: H1 # H2
The test statistic is
(Round to two decimal places as needed.)
