A random sample of 35 four-door passenger vehicles had a mean gas mileage, in miles per gallon (mpg), of 25.9 mpg. The estimate had a margin of error of 2.6 mpg at a 98% confidence
level. Of the following, which is the most plausible value for the true mean gas mileage of all
four-door passenger vehicles?
А
24 mpg
В
29 mpg
С
32 mpg
D
35 mpg

37 1/3

Turn you mixed numbers into fractions 8 becomes 8/1 and 4 2/3 becomes 14/3. Then you multiply the numerators to get 112 (8 × 14=112) as you new numerator. Then multiply your denominators to get 3 (1 × 3=3) as you big denominator. Your improper fraction is gonna be 112/3 then you turn it into a mixed number by finding out how many times 3 goes into 112 to get your whole number (37) with 1/3 leftover. If you need me to explain anything any more just tell me :).
