Answer:
\hat{p}=0.28

Explanation:

Given : Tonya interviews an SRS of 50 of the 175 students living in the dormitory.

i.e. Sample size : n= 50

Number of students think the dorm food is good: x = 14

Now , the numerical value of the sample proportion p from Tonya's sample:


\hat{p}=(x)/(n)


=(14)/(50)=0.28

Hence, the numerical value of the sample proportion p from Tonya's sample is 0.28.
