Question

High Ahr = mrcnt With low salary Sample mean, sample standard deviation, sample size given. Use the one-sample t-test to perform the required hypothesis test about the mean, H, of the population from which the sample was drawn. Use the critical-value approach. Î± = 0.01. A) Test statistic t = 1.47. Critical value: t = 2.821. Do not reject Ho: There is not sufficient evidence to support the claim that the mean is greater than -2.85. B) Test statistic t = 1.47. Critical value: t = 2.896. Reject Ho: There is sufficient evidence to support the claim that the mean is greater than 2.85. C) Test statistic t = 1.47. Critical value: t = 2.896. Do not reject Ho: There is not sufficient evidence to support the claim that the mean is greater than 2.85. D) Test statistic t = 1.47. Critical value: t = 2.33. Do not reject Ho: There is not sufficient evidence to support the claim that the mean is greater than 2.85.

Sample mean, sample standard deviation, sample size given. Use the one-sample t-test to perform the required hypothesis test about the mean, H, of the population from which the sample was drawn. Use the critical-value approach. Î± = 0.01. 
A) Test statistic t = 1.47. Critical value: t = 2.821. Do not reject Ho: There is not sufficient evidence to support the claim that the mean is greater than -2.85.
B) Test statistic t = 1.47. Critical value: t = 2.896. Reject Ho: There is sufficient evidence to support the claim that the mean is greater than 2.85.
C) Test statistic t = 1.47. Critical value: t = 2.896. Do not reject Ho: There is not sufficient evidence to support the claim that the mean is greater than 2.85.
D) Test statistic t = 1.47. Critical value: t = 2.33. Do not reject Ho: There is not sufficient evidence to support the claim that the mean is greater than 2.85.
