Consider the hypotheses below. Upper H 0: mu greater than or equals 65 Upper H 1: mu less than 65 Given that x overbar equals 57.3, s equals 9.7, nequals25, and alphaequals0.10, complete parts 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 to separate answers as needed.) Determine the test statistic, t Subscript x overbar. t Subscript x overbarequals nothing (Round to two decimal places as needed.) What conclusion should be drawn? A. Do not reject Upper H 0. There is not sufficient evidence to conclude that muless than65. B. Reject Upper H 0. There is not sufficient evidence to conclude that muless than65. C. Do not reject Upper H 0. There is sufficient evidence to conclude that muless than65. D. Reject Upper H 0. There is sufficient evidence to conclude that muless than65. b) Use technology to determine the p-value for this test. p-valueequals nothing (Round to three decimal places as needed.)
