2.2

the denominators will be 20 for these two fractions. Problem 2.1d, on the other hand, asks for the "per- centage of the single respondents who live in Complex B." and the denominator for this fraction will be 4 + 6, or 10.) Complex A 5 8 Complex B 10 2 NO 00 Status Married Unmarried ("living together Single Separated Widowed Divorced 8-ON 8 20 20 a. What percentage of the respondents in each com- plex are married? b. What is the ratio of single to married respondents at each complex? c. What proportion of the residents of each complex are widowed? d. What percentage of the single respondents live in Complex B? e. What is the ratio of the "unmarried living together" to the married" at each complex? 2.2 At St. Winnefred Hospital, the numbers of males and females in various job categories are as follows: Job Males Females TOTALS Doctor 83 15 98 Nurse 62 178 Orderly 151 12 163 Lab technician 32 62 Administrator 12 Clerk 72 141 213 TOTALS 412 315 727 Read each question carefully before constructing the fraction and solving for the answer. (HINT: Be sure you place the proper number in the denominator of each frac- tion. For example, some problems use the total number of males or females as the denominator, whereas others use the total number of subjects.) a. What percentage of nurses are male? h. What proportion of orderlies are female? c. For doctors, what is the ratio of males to females? d. What percentage of the total staff are males? e.

Calculate the homicide rate per 100,000 popula- tion for each state and each province for each year. Relatively speaking, which state and which prov- ince had the highest homicide rates in each year? Which society seems to have the higher homicide rate? Write a paragraph describing these results, b. Using the rates you calculated in parte, calculate the percent change between 1997 and 2010 for each state and each province. Which states and provinces had the largest increase and decrease?
