Answer
a. True
Step-by-step explanation:
Based on this survey we estimate that about
of the college students smokes. And a
confidence interval is
. So we know that
our estimative for the smoking rate is in the confidence interval with
certainty. We also know the estimative for the smoking rate in the general population is
. So we can write the two possible hypothesis:
Smoking rate is equal to
.
Smoking rate is not equal to
.
We will reject the null hypothesis
if the estimate doesn't fall into the confidence interval for the college students smoking rate.
Since this condition holds we reject the null hypothesis. So with
certainty we say that the smoking rate for the general population is different than the smoking rate for the college students.

Answer:
a = (15-11b)/7
Step-by-step explanation:
19a + 11b = 12a + 15
Subtract 12a from each side
19a-12a + 11b = 12a-12a + 15
7a +11b = 15
Subtract 11b from each side
7a+11b-11b = 15 -11b
7a = 15-11b
Divide by 7
7a/7 = (15-11b)/7
a = (15-11b)/7
