Answer:


And for this case since the confidence interval contains the value 0 we don't have significant evidence that we have a net change in the levels
Step-by-step explanation:
For this case we have the following info given:
represent the sample size
represent the sample mean
represent the sample deviation
We can calculate the confidence interval for the mean with the following formula:

The confidence level is 0.90 then the significance level would be
and the degrees of freedom are given by:

And the critical value for this case would be:

And replacing we got:


And for this case since the confidence interval contains the value 0 we don't have significant evidence that we have a net change or efectiveness in the levels
A. 10 feet. 1 inch = 5 feet. 2 inches = 10 feet.
The answer is the y- intercept.

Answer:
3/8
Step-by-step explanation:
Answer:
Point C which is 1.
Step-by-step explanation:
A = -6
E = 8
M = (A + E)/2
M = (-6 + 8)/2 = 2/2 = 1
The midpoint is 1 which is point C.
