6. True or False? The null hypothesis indicates that there is no difference while the alternative hypothesis indicates that there is a difference between the means of two groups.
Homework Answers
Null Hypothesis (H0) is a statement of no difference or no relationship
The alternative hypothesis is the hypothesis used in hypothesis testing that is contrary to the null hypothesis. It is usually taken to be that the observations are the result of a real effect (with some amount of chance variation superposed).
The null hypothesis indicates that there is no difference while the alternative hypothesis indicates that there is a difference between the means of two groups.

The null and alternative hypotheses for a hypothesis test of the difference in two population means are: Null Hypothesis: Alternative Hypothesis: 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. Question 4 options: 0.0512 1.99 0.0256 -1.99

The null and alternative hypotheses for a hypothesis test of the difference in two population means are: Null Hypothesis: Alternative Hypothesis: 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. Question 2 options: 3.25 -3.25 0.0043 0.00215

If the ANOVA test is significant, what does that tell us? It indicates which means differ significantly from each other. It indicates that all means are the same. It indicates that there is a difference somewhere between at least two of the groups being compared. It indicates that the null hypothesis is true.
