Question

Find the mean, median, and mode of the following data. If necessary, round to one more decimal place than the largest number of decimal places given in the data.

Rate of Fatal Alcohol Impaired
Car Crashes per 100 Million
Vehicle Miles of Travel
0.30 0.42 0.77 0.28 0.30
0.74 0.50 0.72 0.78 0.30
0.53 0.48 0.57 0.29 0.57
0.44 0.53 0.47 0.49 0.55

Answer 1

a)
`\=x=0.502`

b)
`Median=0.495`

c)
`Mode=0.30`

Explanation:

From the question we are told that:

Miles of travel

0.30 0.42 0.77 0.28 0.30

0.74 0.50 0.72 0.78 0.30

0.53 0.48 0.57 0.29 0.57

0.44 0.53 0.47 0.49 0.55

Sample size n=20

a)

Generally the equation for Mean is mathematically given by

`\=x=(\sum m)/(n)`

`\=x=(10.3)/(20)`

`\=x=0.502`

b)

Generally the equation for Median is mathematically given by

`Median=(10th+11th)/(2)`

`Median=(0.49+0.50)/(2)`

`Median=0.495`

c)

Mode

The Highest occurring Number

`Mode=0.30`
