WHAT IS THE CRITICAL VALUE PLEASE
 
Assume that you have a sample of
n1=8​,
with the sample mean
X1=41​,
and a sample standard deviation of
S1=6,
and you have an independent sample of
n2=14
from another population with a sample mean of
X2=34
and the sample standard deviation
S2=5.
Complete parts​ (a) through​ (d) below.
 
 
 
a. What is the value of the​ pooled-variance
tSTAT
test statistic for testing
H0: μ1=μ2​?
 
tSTAT=2.942.94
​(Round to two decimal places as​ needed.)
b. In finding the critical​ value, how many degrees of freedom are​ there?
 
2020
degrees of freedom
