It’s 4/3. Count up 4 and go over 3.
Answer:
We need a sample of at least 1797 if we wish to be 95% confident that the sample percentage of those equating success with personal satisfaction is within 2.3% of the population percentage.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error is:
95% confidence level
So , z is the value of Z that has a pvalue of , so .
In this problem, we have that:
How large a sample is needed if we wish to be 95% confident that the sample percentage of those equating success with personal satisfaction is within 2.3% of the population percentage?
We have to find n for which . So
We need a sample of at least 1797 if we wish to be 95% confident that the sample percentage of those equating success with personal satisfaction is within 2.3% of the population percentage.
Answer:
It would be the third answer choice
Step-by-step explanation:
Answer:
First, we need to find the slope.
Slope = change in y/change in x
= -5 - 0/0 - 2
= -5/-2
= 2.5 or just 5/2 so the answer is 2.5
Step-by-step explanation:
Answer:
L = 8
Step-by-step explanation:
The volume of a rectangular prism is found by V = L*h*w. Substitute V = 120, w = 5 and h =3 then solve for the length.
120 = L*3*5
120 = 15L
8 = L
