Check answer
For part (c), similarly, the probability of obtaining a value less than or equal to
Step 1 :Given that the sample size
Step 2 :The sampling distribution of the proportion is approximately normal if
Step 3 :Calculate the mean
Step 4 :For part (b), we can use the normal approximation to the binomial distribution to calculate the probability. The z-score for a value
Step 5 :For part (c), similarly, the probability of obtaining a value less than or equal to
