Answer:the length is 10
Step-by-step explanation:
since m is the midpoint it is 3 away from y on the x axis and 4 away on the y axis
so if you go the same distance away from the midpoint you get -2, 11
so -2 is 6 away from 4 away and 3 is 8 away from 11
6^2 = 36
8^2 = 64
36+64= 100
the square root of 100 is 10
Answer:
The confidence interval is (24116.3878,24883.6122).
Step-by-step explanation:
We are given the following information in the question:
Population mean,
= $23,500
Sample mean,
= $24,500
Sample standard deviation,s = $2,800
Sample size, n = 146
Confidence interval:
Putting the values, we get,
The confidence interval is (24116.3878,24883.6122).
