About 190 million drivers are registered in the United States. While on a trip with her family, a student counted the number of male drivers and female drivers on the road. There were 58 male drivers and 48 female drivers. Using the sample predict the number of female drivers out of 190 million, rounded to the nearest million.
Fraction of female drivers = 48/106
= 24/53
So according to this experimental data
number of female drivers
= (48/106)(190 million)
= appr 86 million
Thank you
To predict the number of female drivers out of 190 million, we can use the sample of male and female drivers obtained by the student.
First, let's calculate the proportion of female drivers in the sample:
Proportion of female drivers = Number of female drivers in the sample / Total number of drivers in the sample
Proportion of female drivers = 48 / (58 + 48)
Proportion of female drivers ≈ 0.4528
Next, we can use this proportion to estimate the number of female drivers out of 190 million:
Number of female drivers = Proportion of female drivers * Total number of drivers in the population
Number of female drivers ≈ 0.4528 * 190 million
Number of female drivers ≈ 86 million
Rounded to the nearest million, the estimated number of female drivers out of 190 million is 86 million.
