Select one:

a. 0.308

A two-sided significance test for two population proportions is to be performed using the P-value approach. Ho: p₁- p₂= 0, vs Ha: p₁- p₂ 0 . Use the given sample data to find the P-value for the significance test. Give an interpretation of the P-value.n1n1 = 200, p1p1^ = 0.10, n2n2 = 200, p2p2^ = 0.08.

Select one:

a. P-value = 0.2119; There is about a 21.19% chance that the two proportions are equal.

b. P-value = 0.4238; There is about a 42.38% chance that the two proportions are equal.

c. P-value = 0.484; If there is no difference in the proportions, there is about a 48.4% chance of seeing the observed difference or larger by natural sampling variation.

d. P-value = 0.484; If there is a difference in the proportions, there is a 48.4% chance of seeing the observed difference by natural sampling variation.

e. P-value = 0.2119; If there is no difference in the proportions, there is about a 21.19% chance of seeing the observed difference or larger by natural sampling variation.
