mean difference in tuition. Determine if all the appropriate
conditions and assumptions satisfied. (Ignore the possibility
of state-specific laws.) Select all that apply.
A. Yes, all the conditions are definitely satisfied.
B. No, the Independent Groups Assumption is definitely not
satisfied.
C. No, the Independence Assumption is definitely not
satisfied.
D. No, the Nearly Normal Condition is definitely not
satisfied.
E. No, the sample size in not large enough to ensure that the
CLT applies.
F. No, the Paired Data Condition is not satisfied.
G. No, it is impossible to determine if the Independence
Assumption is satisfied.
H. No, it is impossible to determine if the Nearly Normal
Condition is satisfied.
I.No, it is impossible to determine if the Independent Groups
Assumption is satisfied.
J.No, it is impossible to determine if the Paired Data
Condition is satisfied.
b) Create a 95% confidence interval for the mean difference in
cost taking account of what you found in part a, and
interpret your interval in context. Let each difference be equal to
the nonresident tuition minus the resident tuition.
A.With 95% confidence, the nonresidents pay,
on average, more than residents by a value between
($__,$__).
B.For all samples, 95% of them will have a mean
difference that falls within the
confidence interval, ($__,$__).
C.The confidence interval, ($__,$__).contains the true
value that nonresidents pay more than residents,
on average, 95% of the time.
D.Any difference will fall within ($__,$__). 95% of
the time.
c) A national magazine claims that public institutions charge
state residents an average of $12700 less for tuition each
semester. What does the confidence interval from part b indicate
about this assertion?
A.The assertion is not reasonable since $12700 is not
in the confidence interval.
B.The assertion is reasonable because $12700 is approximately
equal to the mean difference.
C.The assertion is not reasonable because $12700 is not close
to the mean difference.
D.The assertion is reasonable since $12700 is in the confidence
interval.
