A population has a mean of 50 and a standard deviation of 7. You select a random sample of 36. Compute the following:
The value for which there is a .025 probability that the sample mean will be greater than.
-----
Find the t-score that has a 0.025 left-tail.
-----
invT(0.025,35) = -2.0301
------
Find the corresponding "x-value":
x = ts + u
x = -2.0301*(7/sqrt(36)) + 50
----
x = 47.63..
