Question

Will each of the following increase, decrease, or have no effect on the value of the test statistic in a one-independent sample t-test?

(a) The sample size is increased. This change will increase the value of the test statistic. This change will decrease the value of the test statistic. This change will have no effect on the value of the test statistic.

(b) The sample variance is doubled. This change will increase the value of the test statistic. This change will decrease the value of the test statistic. This change will have no effect on the value of the test statistic.

(c) The level of significance is reduced from 0.05 to 0.01. This change will increase the value of the test statistic. This change will decrease the value of the test statistic. This change will have no effect on the value of the test statistic

. (d) The difference between the sample and population mean increased. This change will increase the value of the test statistic. This change will decrease the value of the test statistic. This change will have no effect on the value of the test statistic.
