= . Suppose we want to test the null hypothesis Ho: p = 0.34 against the alternative hypothesis H1: p > 0.34. Suppose also that we observed 120 successes in a random sample of 300 subjects and the level of significance is 0.05. What is the p-value for this test? Select one: a. 0.9857 O b. 0.4 O c. 0.05 O d. 0.0143
When conducting a hypothesis test about p we can assume the test statistic Z - P-P p(1-P) n approximately follows a standard normal distribution if: Select one: a. the data is continuous O b. the data is normally distributed O c. np > 5 \\ | or \\ \n(1 – p) > 5 O d. np > 5\ \ \ and \ \ \ n(1 – p) > 5
- = Suppose we want to test the null hypothesis Ho: p1 - P2 = 0.12 against the alternative hypothesis H1:21 - P2 > 0.12 at the 5% level of significance. Suppose also that - ội - 0.8, ni = 500, 2 - 0.75, n2 = 400. What is the observed test statistic for this test? Select one: a. 1.659 O b. 1.780 C. -2.492 d. 1.793
