Answer:
The t-score of 2.715 should be used
Step-by-step explanation:
Degrees of freedom ==> n - 1 ==> 38 - 1 ==> 37
to find 99% confidence interval, Hence,
Find t0.005 in front of 37 degrees of freedom,
Therefore the answer is, t-score = 2.715
X= unknown variable (original tuition cost)
12% of x=$138
can also be written as
0.12x=$138
Divide both sides by 0.12 to isolate x
x=138/0.12
x= 1150
