The average amount of money spent for lunch per person in the college cafeteria is $6.75 and the standard deviation is $2.54. Suppose that 10 randomly selected lunch patrons are observed. Assume the distribution of money spent is normal, and round all answers to 4 decimal places where possible. For a single randomly selected lunch patron, find the probability that this patron's lunch cost is between $7.2652 and $7.7368. Incorrect For the group of 10 patrons, find the probability that the average lunch cost is between $7.2652 and $7.7368.
