Step-by-step explanation:
The formula to calculate the confidence interval is given by :-
, where n= sample size .
= sample proportion.
z* = cRitical value .
Let p be the population proportion of students who receive some financial aid.
The dean randomly selects 200 students and finds that 118 of them are receiving financial aid.
i.e. n= 200
We know that the critical value for 95% confidence interval : z*= 1.96
Then, the 95% confidence interval for population proportion will be :-
Hence, 95% confidence interval to estimate the proportion of students on financial aid =
First find 7.5% of 322.35
322.35 X .075 = 24.18
Now add this to the flight cost
322.35 + 24.18 = 346.53
