Question

a researcher claims that 62% of voters favor gun control. determine whether the hypothesis test for this claim is left - tailed, right - tailed, or two - tailed.
a. left - tailed
b. right - tailed
c. two - tailed

Explanation:

A claim about a proportion (here, 62% of voters favoring gun control) in a hypothesis test is two - tailed when we are simply testing if the proportion is different from a given value. Since the claim is just about the proportion being 62% (not greater than or less than in a one - sided sense), it is a two - tailed test.

Answer:

C. two - tailed
