Question: Haagen-Dazs ice cream produces a frozen yogurt aimed at health-conscious ice cream lovers. Before marketing the product in 2007, the company wanted to estimate the proportion of grocery stores currently selling Haagen-Dazs ice cream that would sell the new product. If 60% of the grocery stores would sell the product and a random sample of 200 stores is selected, what is the probability that the percentage in the sample will deviate from the population percentage by no more than 7 percentage points?
