Extra Credit True or False (T/F): a. A Type l error in hypothesis testing is to accept the null hypothesis when it is really false. b. A two-sided t-statistic below 1.96 is always not significant (i.e., will alwnys accept Ho) at the 5% level of significance. c. The degrees of freedom for a two-sided t-test of the difference in two population means assuming unequal variances never exceedsn +m- 2 where n and m are the sample sizes of the two populations. d. If the confidence interval for a two-sided t-test of whether two population means are not significantly different includes zero, the conclusion is to reject the null hypothesis. e. Increasing the sample size of an experiment (without increasing the variance) decreases the size of the t-statistic. CS Scanned with CamScanner
