are given. Use the one -mean t-test to perform the requirga hypothesis

A sample mean, sample standard deviation, and sample size are given. Use the one -mean t-test to perform the requirga hypothesis test about the mean, u, of the population from which the sample was drawn. Use the I -value approach. Also assess the strength of the evidence against the null hypothesis. 15) 15) x = 226,450, s = 11,500, n - 23, Ho: H = 220,000, Ha: [ > 220,000, a = 0.01 A) Test statistic: t = 2.69, P-value = 0.9933. Do not reject the null hypothesis. There is not sufficient evidence to conclude that the mean is greater than 220,000. The evidence against the null hypothesis is weak or none. B) Test statistic, t = 2.69, P-value = 0.00669. Reject the null hypothesis. There is sufficient evidence to conclude that the mean is greater than 220,000. The evidence against the null hypothesis is very strong. C) Test statistic: t = 0.56, P-value = 0.2877. Do not reject the null hypothesis. There is not sufficient evidence to conclude that the mean is greater than 220,000. The evidence against the null hypothesis is weak or none. D) Test statistic: t = 2.69, P-value = 0.0036. Reject the null hypothesis. There is sufficient evidence to conclude that the mean is greater than 220,000. The evidence against the null hypothesis is very strong. s are listed in the table. 16)
