Question :- 1. If we are testing for the difference between two population means and assume that the two populations have equal and unknown standard deviations, the degrees of freedom are computed as (n 1 )(n 2 ) - 1. T/F 2. When dependent samples are used to test for differences in the means, we compute paired differences. T/F 3.Suppose we test the difference between two proportions at the 0.05 level of significance. If the computed z is -1.07, what is our decision? Select one: a. Reject the null hypothesis b. Do not reject the null hypothesis c. Take a larger sample d. Reserve judgment 4. The level of significance is the risk of rejecting the null hypothesis when it is actually true. T?F 5. What are the two critical values for a two-tailed test with a 0.01 level of significance when n is large and the population standard deviation is known? Select one: a. Above 1.96 and below -1.96 b. Above 1.65 and below -1.65 c. Above 2.58 and below -2.58 d. Above 1.00 and below -1.00 6. The paired difference test has ( n - 1) degrees of freedom. T/F 7.
