The null and alternative hypotheses for a hypothesis test of the difference in two population means...

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

Answer 1

Answer #1

Answer: 0.00215

Given:This is One tailed test.

Null Hypothesis: The difference between two population mean are equal.

Alternative Hypothesis: The difference between two population mean are less or greater equal. [given one tailed test]

P value is 0.0043/2=0.00215
