A school administrator wants to see if there is a difference in the number of students per class for Portland Public School district (group 1) compared to the Beaverton School district (group 2). Assume the populations are normally distributed with unequal variances. A random sample of 26 Portland classes found a mean of 35 students per class with a standard deviation of 4.

Use technology to find the critical value using df = 41.6021 and round answers to 4 decimal places.
