A grocery store's receipts show that Sunday customer purchases have a skewed distribution with a mean of $30 and a standard deviation of $20. Suppose the store had 309 customers this Sunday. a) Estimate the probability that the store's revenues were at least $9,800. b) If, on a typical Sunday, the store serves 309 customers, how much does the store take in on the worst 1% of such days? a) The probability is (Round to four decimal places as needed.)

Suppose that the distribution of the grades of students in MAPEH performance 1 is roughly normally distributed with a mean of 85 and a standard deviation of 5 a. Between what values do we expect the grades of the middle 68% of the MAPEH students in performance 1 lie? b.
