?(Type a whole? number.)

Answer 1

Answer:

66%

Step-by-step explanation:

Given :

Age          Percentile

75           97

65           90

55           78

45           58

35           37

25           13

20           66

To Find :The percentage of drivers who are younger than 20 is _____%.

Solution:

Refer the given table

The percentile corresponding to age 20 is 66.

Percentile : A data item is said to be in nth percentile of distribution if n% of the distribution are less than that particular data item.

So, drivers who are younger than 20 are said to be in 66 percentile if 66%of the distribution are less than that particular data item.

Hence The percentage of drivers who are younger than 20 is 66%.

Answer 2

Answer:

6%

Step-by-step explanation:

Percentile : A percentile of a number represents the percentage of data fall below that number.

The given table shows the selected ages of licensed drivers in one country and the corresponding percentiles.

Age          Percentile

75                   97

65                  90

55                   78

45                   58

35                   37

25                   13

20                   6

From the given table it is clear that the percentile corresponding to age 20 is 6. It means the age of 6% of the drivers is less than 20.

Therefore, the percentage of drivers who are younger than 20 is 6%.
