2) (25 points) The number of square feet of coverage that you get from a gallon of paint is normally distributed with a mean of 380 square feet and a standard deviation of 30 square feet. A sample of 62 gallons of paint is to be randomly selected. A) Explain how we know that the standard deviation in the number of square feet of coverage can be converted to a Chi-squared score. B) What is the probability that for a sample of 62 randomly selected gallons of paint the standard deviation in the number of square feet of coverage is 28 square feet or less? P(S
