Choosing a Test and Naming the Populations
For each of the following, state whether a one-proportion z-test or a two-proportion z-test would be appropriate, and name the populations.
a. A marketing manager asks a random sample of cricketers and a random sample of soccer players whether they support television commercials during games.
The manager wants to determine whether the proportion of cricketers who support commercials is less than the proportion of soccer players who support these.
