Extracted text: A sample mean, sample standard deviation, and sample size are given. Use the one-mean t-test to perform the required hypothesis test about the mean, µ, of the population from which the sample was drawn. Use the critical-value approach. x= 24.4, s = 9.2, n= 25, Ho: H = 26, Hạ:µ < 26,="" a="0.05" %3d="" .="" ..="" o="" a.="" test="" statistic:="" t="-" 4.35.="" critical="" value:="" t="-" 1.708.="" reject="" ho.="" there="" is="" sufficient="" evidence="" to="" conclude="" that="" the="" mean="" is="" less="" than="" 26.="" o="" b.="" test="" statistic:="" t="-" 4.35.="" critical="" value:="" t="-" 1.711.="" reject="" ho.="" there="" is="" sufficient="" evidence="" to="" conclude="" that="" the="" mean="" is="" less="" than="" 26.="" o="" c.="" test="" statistic:="" t="-" 0.87.="" critical="" value:="" t="-" 1.708.="" do="" not="" reject="" ho.="" there="" is="" not="" sufficient="" evidence="" to="" conclude="" that="" the="" mean="" is="" less="" than="" 26.="" o="" d.="" test="" statistic:="" t="-" 0.87.="" critical="" value:="" t="-" 1.711.="" do="" not="" reject="" ho.="" there="" is="" not="" sufficient="" evidence="" to="" conclude="" that="" the="" mean="" is="" less="" than="">
