Sample : 129 UC Berkeley Undergraduates
2)
Can the results of the study be generalized to the population of interest?

Answer:
He must score 83 in the last test.
Step-by-step explanation:
To get a mean of 80 Terry must score a total of 4*80 = 320 over the 4 tests.
So his score for the last test must be 320 - (71 + 80 + 86)
= 320 - 237
= 83.
The conversion formula is f = (9/5) c + 32 [ The 95c is very confusing!]
(9/5)c = f - 32
Multiply both sides by 5/9:-
c = (5/9) ( f - 32)
That's option a).
