Expert Solution

The test statistic is t= 1.29

The​ P-value is 0.218

Failed to reject the null hypothesis. The data is not sufficient evidence to conclude that the mean is different than 27

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 M of the population from which the sample was drawn. Use the P- value approach. Also asses the strength of the evidence against the null hypothesis. Mean of the sample= 226,450 ; S= 11,500 ; n= 23 ; mean of the population = 220, 000 ; Ha : M>220,000 ; alpha = 0.01 . 2)....

A sample size of 120 had a sample mean and standard deviation of 100 and 15 respectively. Of these 120 data values, 3 were less than 70, 18 were between 70 and 85, 30 between 85 and 100, 35 between 100 and 115, 32 were between 115 and 130 and 2 were greater than 130. Test the hypothesis that the sample distribution was normal.
