aved The null and alternative hypotheses for a hypothesis test of the difference in two population means are: Question 3 (3 points) Saved What are the inputs to ttest_ind method in the scipy module? Select one. O null and alternative hypothesis values Null Hypothesis: M1 = 42 Odataframes of values from each sample and optional equal variance indicator Alternative Hypothesis: Mi 7 M2 Oz-score and the corresponding P-value Notice that the alternative hypothesis is a two-tailed test. Suppose ttest_ind method from scipy module is used to perform the test and the output is (-1.99, 0.0512). What is the P-value for this hypothesis test? Select one. O test statistic and the P-value O 0.0512 Question 4 (3 points) Saved In this course, the Python methods for hypothesis tests return two-tailed probability values. Suppose a one-tailed alternative hypothesis is used. How can you obtain a one-tailed probability value (P-Value)? Select one. O 1.99 0.0256 O Divide the result by 2 O -1.99 Divide the result by 4 O Multiply the result by 4 Question 2 (3 points) Saved The null and alternative hypotheses for a hypothesis test of the difference in two population proportions are: O Multiply the result by 2 Null Hypothesis: p1 = P2 Question 5 (3 points) Saved The null and alternative hypotheses for a hypothesis test of the difference in two population means are: Alternative Hypothesis: p1 > p2 Null Hypothesis: Hi = uz Notice that the alternative hypothesis is a one-tailed test. Suppose proportions_ztest method from statsmodels is used to perform the test and the output is (1.13, 0.263). What is the P-value for this hypothesis test? Select one. Alternative Hypothesis: My < u2 1.13 Notice that the alternative hypothesis is a one-tailed test. Suppose ttest_ind method from scipy module is used to perform the test and the output is (3.25, 0.0043). What is the P-value for this hypothesis test? Select one. O 0.263 O 0.00215 0-1.13 0.0043 O 3.25 0.1315 O-3.25
