Anastaziya [24]

Answer: Part A : c = n.p

Part B = 366 moviegoers

Step-by-step explanation: In part A, to predict the number of moviegoers, we have to find the <u>proportion</u> of the sample that does the activity, which will called <u>p</u>. Since <u>p</u> is a percentage, to determine how many moviegoers are seeing a comedy, you multiply it by the sample size, <u>n</u>.

Therefore: c = n.p

For part B, based on the the sample:

p = \frac{42}{175} = 0.24

The total population is given: 1,525

c = 0.24.1,525

c = 366

Based on the sample, <u>366</u> <u>people</u> are seeing a comedy.
