Question 1

1.

A survey was conducted to determine the amount of exercise people of different age groups averaged each week. Create a two-way relative frequency table to display the data. All data is given in minutes of exercise/week. Use the data to identify at least two different trends.

Age 10-19: 0-30 = 8
30-60 = 12
60+ = 3
Age 20-29: 0-30 = 11
30-60 = 14
60+ = 7
Age 30-39: 0-30 = 24
30-60 = 21
60+ = 13
Age 40-49: 0-30 = 21
30-60 = 28
60+ = 9

Question 2

2.

A group of middle school students were asked what their favorite core subject was. Below are the results:

Girls: Math - 23
Science - 31
Reading - 46
Social Studies - 36

Boys: Math - 31
Science - 43
Reading - 21
Social Studies - 17

Create a two-way relative frequency table to demonstrate this data. What is the conditional relative frequency of a student's favorite subject being math? What is the conditional relative frequency of boys favorite subject being social studies?

Question 3

3.

Elementary students were surveyed to determine what type of performer they would most enjoy at their birthday party. The data collected is below:

Kindergardeners: clown - 32
magician - 11
musician 9

1st - 3rd grade students: clown - 21
magician - 33
musician - 13

4th - 5th grade students: clown - 15
magician - 37
musician - 4

Create a two-way relative frequency table to demonstrate the data. What is the conditional relative frequency that a lower-elementary student wanted to see a magician? What is the conditional relative frequency that a student wanted to see a clown? What is one trend you can identify in the data?
