Question

1. A public opinion survey explored the relationship between age and support for increasing the minimum wage. The results are found in the following two-way frequency table. 

a. Complete the two-way frequency table below:

	For	Against	No Opinion	Total
Ages 21 - 40	25	20	5	50
Ages 41 - 60	30	30	15	75
Over 60	50	20	5	75
Total	105	70	25	200

b. Create a two-way relative frequency table that summarizes the data from the table.  

	For	Against	No Opinion	Total
Ages 21 - 40
Ages 41 - 60
Over 60
Total

Use the two-way frequency table and the relative frequency table to answer the following questions:

c. Out of the people that have no opinion, what percentage is over 60 years old?

 

d. What percentage of people want to increase minimum wage? 

 

e. How many people over 60 are against increasing the minimum wage?

 

f. For ages 21-60 how many were for increasing the minimum wage?

 

g. What percent of people over 60 are against or have no opinion? 

Answer 1

b) To find a relative frequency table, divide every value by 200, or the total number data.

0.125 0.10 0.025 0.25

0.15 0.15 0.075 0.375

0.25 0.10 0.025 0.375

0.525 0.35 0.125 1

c) There are 25 people that have no opinion, and 5/25 of those people are 60 or older = 20%

d) 105 people in total want to increase minimum wage. In the relative frequency table this is the bottom left value of 52.5%

e) Out of the 75 people that are over 60, 20 are against increasing the minimum wage

f) Add 25 and 30 (first two values in the first column) to get 55, which is the number of people 21-60 who want to increase minimum wage

g) There are 75 people over 60 years old. 20 are against and 5 have no opinion, so 25/75 = 33% of people 60 years old or more are either against or have no opinion.
