Step-by-step explanation:
First off, you want to find the whole number in square root form
1 = √1
2 = √4
3 = √9
4 = √16
5 = √25
You want to find which to numbers √7 is in between
7 is between 4 and 9 so the √7 is in between √4 and √9 which means that √7 is between 2 and 3
The second one is your answer

Answer: (80% , 85%)
Step-by-step explanation:
We know that, confidence interval for population proportion is given by :-
(p-E , p+E)
, where p = sample proportion , E = Margin of error.
Given : Proportion of elementary school teachers who are female = 82%.
The article also states the maximum error of their estimate = 3%.
Then, the 90% confidence interval for the proportion of elementary school teachers who are female will be :
(82%-2% , 82%+3%)
= (80% , 85%)
Hence, the resulting 90% confidence interval for the proportion of elementary school teachers who are female = (80% , 85%)
