Extracted text: The true average diameter of ball bearings of a certain type is supposed to be 0.5 in. A one-sample t test will be carried out to see whether this is the case. What conclusion is appropriate in each of the following situations? (a) n = 19, t = 1.53, a = 0.05 O Reject the null hypothesis. There is sufficient evidence that the true diameter differs from 0.5 in. O Reject the null hypothesis. There is not sufficient evidence that the true diameter differs from 0.5 in. O Do not reject the null hypothesis. There is sufficient evidence that the true diameter differs from 0.5 in. O Do not reject the null hypothesis. There is not sufficient evidence that the true diameter differs from 0.5 in. (b) n = 19, t = -1.53, a = 0.05 O Reject the null hypothesis. There is sufficient evidence that the true diameter differs from 0.5 in. O Reject the null hypothesis. There is not sufficient evidence that the true diameter differs from 0.5 in. O Do not reject the null hypothesis. There is sufficient evidence that the true diameter differs from 0.5 in. O Do not reject the null hypothesis. There is not sufficient evidence that the true diameter differs from 0.5 in. (c) n = 29, t = -2.47, a = 0.01 O Reject the null hypothesis. There is sufficient evidence that the true diameter differs from 0.5 in. O Reject the null hypothesis. There is not sufficient evidence that the true diameter differs from 0.5 in. O Do not reject the null hypothesis. There is sufficient evidence that the true diameter differs from 0.5 in. O Do not reject the null hypothesis. There is not sufficient evidence that the true diameter differs from 0.5 in. (d) n = 29, t = -3.88, a = 0.05 O Reject the null hypothesis. There is sufficient evidence that the true diameter differs from 0.5 in. O Reject the null hypothesis. There is not sufficient evidence that the true diameter differs from 0.5 in. O Do not reject the null hypothesis. There is not sufficient evidence that the true diameter differs from 0.5 in. O Do not reject the null hypothesis.
