Question
You wish to test the following claim (Ha) at a significance
level of a =
0.005.
H.: µ1
а
You obtain a sample of size nį
53.4 and a standard deviation of s1
first population. You obtain a sample of size n2 = 61 with
52 with a mean of
11.5 from the
57.1 and a standard deviation of s2
= 7.2
a mean of 2
from the second population.
You will need to determine whether or not to pool so you
will use the correct df.
What is the critical value for this test? Report answer
accurate to three decimal places.
