Question 20 If an alternative hypothesis is expressed in a non-equalityf statement, it is non-directional. C} always false {I} always true C} sometimes false {I} sometimes true Given at = 1.96 51 2: = 2.0, therefore accept the null and reject the alternative hypothesis. Note: 2t is tabular value 1while 1: is the computed value. C} always false C} sometimes false {I} sometimes false {I} always true \fQuestion 23 To test if observed frequency fits to a theoretical (expected) frequency distribution, is used . O Pearson-r O chi-square O tor z-test O normal distributionQuestion 25 mean = 7 is an example of what hypothesis? O all of the above O alternative O null O one-tailedQuestion 2? Given the alternative hypothesis: "There is no signicant difference in the examination scores of male and female students." The test to be used is____ 0 Either 0 Neither O Two-Tailed Test 0 One-tailed test Question 28 Computed data shows: zt = 2.58, one-tailed, Zz = -3.0; therefore O reject Ho O either O accept Ho O neitherQuestion 29 It is used to test the non-significance of difference among 3 or more groups. O chi-square O ANOVA O t-test O regressionQuestion 30 It is used to test the non-significance of difference between two groups. O regression O t-test O chi-square O ANOVA
