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 91% of the years Y= $0, but in 9% of the years Y=$4000.
The mean treatment expenditure for a minor fracture in any year is $ , and the standard deviation of the treatment expenditure for a minor fracture in any year is $ . (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(Y), in any year is $, and the standard deviation of the average treatment expenditure for a minor fracture in any year is $.
