Answer:
D)We are 95% confident that the proportion of adults (ages 17‐26) who attended college during the past 4 years and say that alcohol and drug use at their school is a big problem is between 53% and 59%.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
95% confidence interval is (0.53, 0.59).
This means that we are 95% sure that the true proportion for the population of adults who attended college who say that alcohol is a big problem is between 0.53 and 0.59. This means that the answer is given by option D.
Answer:
Below in bold.
Step-by-step explanation:
Find the prime factors:-
126 = 2 * 3 * 3 * 7
234 = 2 * 3 * 3 * 13
So the GCF = 2 * 3 * 3 = 18.
The LCM = 2 * 3 * 3 * 7 * 13
= 1638.
((-9+14)/2, (-20+12)/2)
(5/2,-8/2)
(5/2,-4)
This is the concept of algebra, to solve the question we proceed as follows;
the current number of women is:
1/4*20=5 women
the percentage of women is:
1/4*100=25%
therefore for the team to have 40% women, the number of women should be:
40/25*5
=8 women
The answer is 8 women
