Consider the hypotheses below. Upper H 0?: mu greater than orequals 65 Upper H 1?: mu less than 65 Given that x overbar equals57.3?, s equals 9.7?, nequals25?, and alphaequals0.10?, completeparts a and b below. ?a) What conclusion should be? drawn?Determine the critical? value(s). The critical? value(s) is(are)nothing. ?(Round to three decimal places as needed. Use a comma toseparate answers as? needed.) Determine the test? statistic, tSubscript x overbar. t Subscript x overbarequals nothing ?(Round totwo decimal places as? needed.) What conclusion should be? drawn?A. Do not reject Upper H 0. There is not sufficient evidence toconclude that muless than65. B. Reject Upper H 0. There is notsufficient evidence to conclude that muless than65. C. Do notreject Upper H 0. There is sufficient evidence to conclude thatmuless than65. D. Reject Upper H 0. There is sufficient evidence toconclude that muless than65. ?b) Use technology to determine the?p-value for this test. ?p-valueequals nothing ?(Round to threedecimal places as? needed.)
