Answer:
confidence interval for the proportion of all former UF students who are still in love with Tim Tebow.
(0.79 , 0.89)
Step-by-step explanation:
step 1:-
Given sample survey former UF students n = 1532
84% said they were still in love with Tim Tebow
p = 0.84
The survey sampling error
Given standard error of proportion = 2% =0.02
<u>Step 2</u>:-
The 99% of z- interval is 2.57
The 99% of confidence intervals are
p ± zₐ S.E (since sampling error of proportion = 
on simplification , we get
(0.84 - 0.0514 , 0.84 + 0.0514)
(0.79 , 0.89)
<u>conclusion</u>:-
confidence interval for the proportion of all former UF students who are still in love with Tim Tebow.
(0.79 , 0.89)

Answer:
You could drive 2805 miles on 55 gallons of gas
The car's gas mileage is 51 miles per gallon
Step-by-step explanation:
First, find the gas mileage by dividing the given number of miles by the number of gallons:
510/10
= 51
The car's gas mileage is 51 miles.
Find how far you can drive on 55 gallons of gas by multiplying 51 by 55
51(55)
= 2805
So, you can drive 2805 miles.
