Question
Teachers Software analysis of the salaries of a random
sample of 288 Nevada teachers produced the confidence
interval shown below. Which conclusion is correct?
What’s wrong with the others?
t-Interval for m:
with 90.00% Confidence,
38944 6 m1TchPay2 6 42893
a) If we took many random samples of 288 Nevada
teachers, about 9 out of 10 of them would produce this
confidence interval.
b) If we took many random samples of Nevada teachers,
about 9 out of 10 of them would produce a confidence
interval that contained the mean salary of all Nevada
teachers.
c) About 9 out of 10 Nevada teachers earn between
$38,944 and $42,893.
d) About 9 out of 10 of the teachers surveyed earn
between $38,944 and $42,893.
e) We are 90% confident that the average teacher salary
in the United States is between $38,944 and $42,893.
