Suppose they solicit 400 customers one day, and find that 250 of them have a Grayson's card. Assume that 60% of all Grayson's customers have a discount card, what is the probability of getting a sample proportion of at least 250 / 400=0.625?
Construct a frequency distribution of the sample mean, and plot a histogram of this distribution. Use the central limit theorem to calculate and identify the sampling distribution of the sample mean.
