A One-Sample T-Test for the Mean Population Score on an Aptitude

question 4

Multiple Choice

A one-sample t-test for the mean population score on an aptitude test is performed.The hypotheses are: H0: μ = 100
HA: μ ≠ 100
The computer test statistic,t,is positive,and the P-value for the test is found to be 0.07.What is a correct interpretation of this P-value?

• A)If the null hypothesis were true,the probability of observing the test statistic would be 0.07.
• B)If the null hypothesis were true,the observed sample values would occur 7% of the time.
• C)Reject the null.At a significance level of 0.05,there is strong evidence that the mean aptitude score is different from 100.
• D)If the null hypothesis were true,the probability of observing a value of the test statistic as large or larger than that observed would be 0.07.
• E)If the null hypothesis were true,the probability of observing a value of the test statistic as extreme or more extreme than actually observed would be 0.07.
