Based on a simple random sample of 1300 college students, it is found that 299 students own a car. We wish to construct a ${\displaystyle 90\mathrm{\%}}$ confidence interval to estimate the proportions ? of all college students who own a car.
A) Read carefully the text and provide each of the following:
The sample size ${\displaystyle ?=}$
from the sample, the number of college students who own a car is ${\displaystyle ?=}$
the confidence level is ${\displaystyle CL=}$ ${\displaystyle \mathrm{\%}}$.
B) Find the sample proportion ${\displaystyle \widehat{?}=}$
and ${\displaystyle \widehat{?}=1-\widehat{?}=}$
