Question

A researcher wanted to test the ability to perceive a voice from an adjacent room for males versus females who were watching a football game on TV. To do so, he randomly selected 40 males and 40 females and found the mean speaking volume at which they no longer heard the voice of someone calling from the adjacent room. TV volume was held constant. What type of hypothesis test should be done with the data?

a) Paired t-test for two means (Matched-pairs)

b) McNemar’s test

c) A standard t-test for two means (Welch’s t)

d) T-test for one mean

Explanation / Answer

Since males and females are randomly selected, these samples would be independent of each other. Hence,

We will use a standard t-test for two means (Welch’s t).

Option C is correct.
