# Question: Check if the sample size is large enough to use

Check if the sample size is large enough to use the normal distribution to make a confidence interval for p for each of the following cases.

a. n = 50 and p̂ = .25

b. n = 160 and p̂ = .03

c. n = 400 and p̂ = .65

d. n = 75 and p̂ = .06

a. n = 50 and p̂ = .25

b. n = 160 and p̂ = .03

c. n = 400 and p̂ = .65

d. n = 75 and p̂ = .06
