A hospital conducted a study of the waiting time in its emergency room. The hospital has a main campus and three satellite locations. Management had a business objective of reducing waiting time for emergency room cases that did not require immediate attention. To study this, a random sample of 15 emergency room cases that did not require immediate attention were selected at each location on a particular day, and the waiting times were collected and stored – see dataset ERWaiting (the same dataset in both 13th and 14th edition, use either one). a) At the 0.05 level of significance, is there an evidence of a difference in the mean waiting times in the four locations? b) If appropriate, determine which pairs of locations differ in mean waiting time. c) At the 0.05 level of significance, is there an evidence of a difference in the variation in waiting times among the four locations?

is explained in the attachment.

Explanation:

1   all nations face the problem of scarcity because there are limited resources and unlimited wants. nations do not have enough factors of production to produce everything that their population wants. entrepreneurial resources initiate businesses to make new goods and services; labor resources produce goods and services.

2 there are four factors of production: natural resources, labor resources, capital resources, and entrepreneurial resources. natural resources are raw materials from nature that are used to produce goods. trees, water, and grains are natural resources. some natural resources, such as wheat and cattle, are renewable

3 wants

things that you do not need to have in order to survive, but would like to have

needs

things that you must have in order to survive

goods

physical products

services

tasks that a business perform for customers

resources

items that people can use to make or obtain what they need or want

determine
