Answer:
The margin of error is of
Step-by-step explanation:
We have the standard deviation for the sample. So the T-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 10 - 1 = 9
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 9 degrees of freedom(y-axis) and a confidence level of . So we have T = 2.262
The margin of error is:
In which s is the standard deviation of the sample and n is the size of the sample.
Answer:
m=84
r:m = 1:7
therefore when r= 1 then M=14
I think that's how you do it
