The map below shows the percentage change in housing prices from June 2014 to June 2015 in each of nine regions (U.S. Census divisions).† A map of the United States of America is divided into nine regions. The regions and their respective values are as follows. Pacific: 7.68 Mountain: 7.17 West North Central: 3.91 West South Central: 6.92 East North Central: 4.51 East South Central: 4.88 Middle Atlantic: 1.72 South Atlantic: 6.12 New England: 3.18 You are choosing a region of the country to move to. Describe the event E that the region you choose saw a increase in housing prices of 6% or more. E = {Mountain, West North Central, East North Central, Middle Atlantic, East South Central}E = {Pacific, Middle Atlantic, South Atlantic} E = {Pacific, Mountain, South Atlantic, West South Central}E = {West South Central, East South Central, Middle Atlantic, New England}E = {East South Central, Mountain}
A certain health maintenance organization (HMO) wishes to study why patients leave the HMO. A SRS of 360 patients was taken. Data was collected on whether a patient had filed a complaint and, if so, whether the complaint was medical or nonmedical in nature. After a year, a tally from these patients was collected to count number who left the HMO voluntarily. Here are the data on the total number in each group and the number who voluntarily left the HMO: No complaint Medical complaint Nonmedical complaint Total 159 132 69 Left 60 34 26 If the null hypothesis is H0:p1=p2=p3 and using α=0.01, then do the following: (a) Find the expected number of people with no complaint who leave the HMO: (b) Find the expected number of people with a medical complaint who leave the HMO: (c) Find the expected number of people with a nonmedical complaint who leave the HMO: (d) Find the test statistic: (e) Find the degrees of freedom: (f) Find the critical value:
