For this case we have the following expression:
root (q / 36)
We can rewrite the expression.
We have then:
root (q) / root (36)
Then, calculating the square root in the denominator we have:
root (q) / 6
Answer:
root (q) / 6
option A
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 ![[15.1\% ; 21.6\%]](https://tex.z-dn.net/?f=%5B15.1%5C%25%20%3B%2021.6%5C%25%5D)
. 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:
The son is 7, the father is 49.
Step-by-step explanation:
This was a guess-and-check process. I knew this answer was correct because 7*7=49, and 49+7=56.
