Thx for letting us know.
Then what happened?
The formula for the confidence interval is given by
Sample mean + z*[σ/√n], and
Sample mean - z*[σ/√n]
We have:
Sample mean = 23.95
n = 40
σ = 2.55
z* for 99% confidence = 2.58
Substitute these values into the formula, we have
23.95 + (2.58)(2.55÷√40) = 24.99
23.95 - (2.58)(2.55÷√40) = 22.91
So the lower interval is 22.91 and the highest interval is 24.99
M = 1 - 2 / 3 - 1
m = - 1 / 2
It is already rounded to the tens because there is no digit but 0 in the ones digit. I hope this helped.
