Concept explainers
To make two-way table that shows the conditional relative frequencies based on the column totals.
Also to determine conditional relative frequency that a student prefers a cartoon mascot if he or she prefers a hawk as a mascot.
Answer to Problem 24E
Two-way table that shows the conditional relative frequencies based on the column totals.
Tiger | Hawk | Dragon | |
Realistic | |||
Cartoon |
Conditional relative frequency that a student prefers a cartoon mascot if he or she prefers a hawk as a mascot
Explanation of Solution
Given information:
A two-way table
Concept used:
Conditional relative frequency is the ratio of joint relative frequency to marginal relative frequency.
Given table:
Tiger | Hawk | Dragon | Total | |
Realistic | 67 | 74 | 51 | 192 |
Cartoon | 58 | 18 | 24 | 100 |
Total | 125 | 92 | 75 | 292 |
Total
Find joint relative frequency and marginal relative frequency:
Tiger | Hawk | Dragon | |
Realistic | |||
Cartoon | |||
Total | 0.21 | 0.16 | 0.13 |
Two-way table that shows the conditional relative frequencies based on the column totals.
Tiger | Hawk | Dragon | |
Realistic | |||
Cartoon |
Conditional relative frequency that a student prefers a cartoon mascot if he or she prefers a hawk as a mascot
