Level of significance

At a certain college, it is estimated that 25% of the students have cars on campus. Does this seem to be a valid estimate if, in a random sample of 90 college students, 28 are found to have cars? Use a 0.05 level of significance.

Yes

No

Step-by-step explanation:

$$\begin{gathered} q=25\%=\frac{25}{100}=\frac{1}{4}=0.25 \\ n=90 \\ {n}_1=28 \\ \alpha =0.05 \\ x=1 \end{gathered}$$
