Question

According to the Harris Poll, 70 % of dog owners buy their dogs holiday presents. Suppose you select a random sample of 25 dog owners from among the population of 30 dog owners at the dog park. Let X be a random variable equal to the number of dog owners who buy their dogs holiday presents.

Answer 1

The concluding part is missing in the question and it says we should find the probability that 2 of the people selected cook meals for their dogs

Answer:

P(x2) = 0.1857

Step-by-step explanation:

N = 30; since there are 30 people that own dogs

k = 21; since there are 70% of dog owners who buy gifts for their dogs

n = 25; since we randomly select 25 people among the dog owners

x = 2; since we randomly select 2 people who cook meals for their dogs

Therefore, for clarity sake the solution is in the attachment ;

And the probability is 0.1857
