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%)
The formula is Area = ( top + bottom)/2 * height
Using the image:
Area = (20 + 14) / 2 * 9
Area = 34/2 * 9
Area = 17*9
Area = 153 cm^2
The answer is 1,1500 because you ha e to subtract the lowest to highest number
The answer is c. because 6/8 = 3/4 which is equal to the fraction next to it
