1. Is the distribution approximately normal? Why or why not? Answer this in sentence form.
2. Assuming the distribution is approximately normal, calculate the mean and standard deviation. Round both answers to the hundredths place.
3. In a random sample of 600 adults, what is the probability that no more than 40% (at most 40%) have received the bogus email? (Show all work and steps and round the final answer to the hundredths place.)
