hi I need help with this question Which of the following Python functions is used to perform a paired t-test?

Which of the following Python functions is used to perform a paired t-test?

Question options:

a)

ttest(mean1, stdev1, n1, mean2, stdev2, n2, equal_var=False)

b)

ttest_ind(data1, data2, equal_var=False)

c)

ttest_rel(data1, data2)

d)

means_1samp_ttest(mean, std_dev, n, null_value, alternative)

and this question as will

Which of the following Python functions is used to perform a hypothesis test for the difference in two population proportions?

Question 4 options:

a)

prop_hypothesis_test(x, n, null_value, alternative)

b)

prop_1samp_ztest(x, n, null_value, alternative)

c)

prop_1samp_hypothesistest(x, n, null_value, alternative)

d)

proportions_ztest(counts, n)

a)

ttest(mean1, stdev1, n1, mean2, stdev2, n2, equal_var=False)

b)

ttest_ind(data1, data2, equal_var=False)

c)

d)

proportions_ztest(counts, n)

Explanation / Answer

Question 3)

Ans: Option C. ie ttest_rel(data1, data2)

Option B can be used only for those cases when we have equal variance. Ie ttest_ind(data1, data2, equal_var=True)

Question 4)

In python we can use the proportions_ztest function to test the hypothesis for Proportions.

Ans : Option d ie proportions_ztest(counts, n)
