Need to understand how to solve in excel or using megastat. This is practice exam Suppose Bank of America would like to investigate if the credit score and income level of an individual are independent of one another. Bank of America selected a random sample of 400 adults and asked them to report their credit score range and their income range. The following contingency table presents these results. Credit Score Class Less than 650 650–750 More than 750 Income < $50,000 30 24 27 $50,000 ≤ Income < $100,000 42 47 38 $100,000 ≤ Income < $150,000 49 35 26 Income ≥ $150,000 27 29 26 The expected number of individuals with income between $50,000 and $100,000 and a credit score less than 650 is ________.

K Before every flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the aircraft. The aircraft can carry 41 passengers, and a flight has fuel and baggage that allows for a total passenger load of 6,765 lb. The pilot sees that the plane is full and all passengers are men. The aircraft will be overloaded if the mean weight of the passengers is greater than 6,765 lb 41 Should the pilot take any action to correct for an overloaded aircraft? Assume that weights of men are normally distributed with a mean of 183.6 lb and a standard deviation of 35.4. The probability is approximately (Round to four decimal places as needed.)
