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
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?
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?
