Two different simple random samples are drawn from two differentpopulations. The first sample consists of 30 people with 14 havinga common attribute. The second sample consists of 1900 people with1370 of them having the same common attribute. Compare the resultsfrom a hypothesis test of p 1equalsp 2 ?(with a 0.01 significance?level) and a 99?% confidence interval estimate of p 1minusp 2. Whatare the null and alternative hypotheses for the hypothesis? test?A. Upper H 0?: p 1less than or equalsp 2 Upper H 1?: p 1not equalsp2 B. Upper H 0?: p 1not equalsp 2 Upper H 1?: p 1equalsp 2 C. UpperH 0?: p 1equalsp 2 Upper H 1?: p 1less thanp 2 D. Upper H 0?: p1equalsp 2 Upper H 1?: p 1not equalsp 2 E. Upper H 0?: p 1equalsp 2Upper H 1?: p 1greater thanp 2 F. Upper H 0?: p 1greater than orequalsp 2 Upper H 1?: p 1not equalsp 2 Identify the test statistic.nothing ?(Round to two decimal places as? needed.) Identify thecritical? value(s). nothing ?(Round to three decimal places asneeded. Use a comma to separate answers as? needed.) What is theconclusion based on the hypothesis? test? The test statistic is ?not in in the critical? region, so ? reject fail to reject the nullhypothesis. There is ? sufficient insufficient evidence to concludethat p 1not equalsp 2. The 99?% confidence interval is nothinglessthanleft parenthesis p 1 minus p 2 right parenthesisless thannothing. ?(Round to three decimal places as? needed.) What is theconclusion based on the confidence? interval? Since 0 is ? notincluded included in the? interval, it indicates to ? reject failto reject the null hypothesis. How do the results from thehypothesis test and the confidence interval? compare? The resultsare ? the same different ?, since the hypothesis test suggests thatp 1 ? greater than equals less than or equals greater than orequals less than not equals p 2?, and the confidence intervalsuggests that p 1 ? greater than or equals less than greater thanless than or equals not equals equals p 2.
