A popular television show recently had a 22% market share, which means that 22% were tuned to this show. Assume that an advertiser wants to verify that 22% share value by conducting its own survey with 10 households having TV sets in use at the time of the broadcast. What is the mean number of TV sets tuned into the show

2.2

Step-by-step explanation:

Given that:

the proportion of people that tuned the show = 0.22

sample size n = 10

We can compute the mean number of TV sets tuned into the show by using the formula;

10 × 0.22

 2.2

Thus, the mean number of TV sets that tuned into the show = 2.2

step-by-step explanation:
