Answer 1

The estimate of the people is the expected value of the people

279 people would recommend the play to their friends

The estimate of people that would recommend play to their friends

The given parameters are:

• Sample size (n) = 40
• People who recommend play (x) = 31
• Population (N) = 360

The estimate of people that would recommend play to their friends is calculated using:

E(x) =x/n * N

This gives

E(x) = 31/40 * 360

Evaluate the product

E(x) = 279

Hence, 279 people would recommend the play to their friends
