Convert this table to a relative frequency table.
Expert Solution & Answer

To determine
Find the relative frequency distribution for the car type data.
Answer to Problem 1E
The relative frequency distribution is:
Automobile fatalities | Relative frequency |
Subcompact and Mini | 0.2658 |
Compact | 0.2084 |
Intermediate | 0.3006 |
Full | 0.2069 |
Unknown | 0.0183 |
Total | 1.00 |
Explanation of Solution
Given info:
The table represents the type of cars, where the number of passenger in car occupants killed by those car type that killed in accident with year 2011 with frequency.
Calculation:
Relative frequency:
The general formula for the relative frequency is,
The relative frequencies for the remaining types of cars are obtained below:
Automobile fatalities | Frequency | Relative frequency |
