Continuous of the question: The average amount of money spent for lunch per person in the college cafeteria is $ 5.79 and the standard deviation is $ 2.31. Suppose that 8 randomly selected lunch patrons are observed. Assume the distribution of money spent is normal, and round all answers to 4 decimal places where possible.

c. For a single randomly selected lunch patron, find the probability that this patron's lunch cost is between
$6.535 and $7.6334.
d. For the group of 8 patrons, find the probability that the average lunch cost is between $6.535 and
$7.6334.
e. For part d), is the assumption that the distribution is normal necessary? ONo Yes
