K In any year, a person can suffer from a minor fracture From year to year, the number of people seeking treatment for such fractures is random. Let Y denote the treatment expenditure for a minor fracture in any given year. Suppose that in 92% of the years Y=$0, but in 8% of the years Y= $4,000. The mean treatment expenditure for a minor fracture in any year is $ 320.00, and the standard deviation of the treatment expenditure for a minor fracture in any year is $ 1085.17 (Round your answers to two decimal places) Consider a group of 324 people whose lives, homes, and occupations are sufficiently dispersed so that, in any year, the treatment expenditure for a minor fracture of different persons can be viewed as independently distributed random variables. Let Y denote the average treatment expenditure for a minor fracture of these 324 persons in a year The expected value of the average treatment expenditure for a minor fracture, E, in any year is $ and the standard deviation of the average treatment expenditure for a minor fracture in any years s (Round your answers to two decimal places) Incorrect:
