Question

For a hypothesis test of means, we believe the null hypothesis to be equal to 11 units. On a sample size of n = 25, the sample mean was 12.3 units with a standard deviation of 5.5 units. We are concerned that the true mean is greater than the null hypothesis. The t-score and p-values are:
A) t-score = -0.3833. P-Value = 0.3529

B) t-score-1.857. P-Value 0.0378

C) t-score 1.182. P-Value = 0.1244

D) t-score 2.474. P-Value = 0.0093
