Assume that you have a sample of n 1 equals 8, with the sample mean upper x overbar 1 equals 45, and a sample standard deviation of upper s 1 equals 5 comma and you have an independent sample of n 2 equals 17 from another population with a sample mean of upper x overbar 2 equals 34 and the sample standard deviation upper s 2 equals 8. complete parts (a) through (d) below.
a. what is the value of the pooled-variance t subscript stat test statistic for testing upper h 0 : mu 1 equals mu 2?
b. in finding the critical value, how many degrees of freedom are there?
