![QUESTION 6
A group of researchers wanted to determine
if the mean HDL of male patients is less than
female patients. HDL from one hundred
patients were collected and results are as
follows:
n
Gender
Male
28
Female 72
Do these results show sufficient evidence
that the mean HDL of male patients is less
than female patients? Test at 5% level of
significance.
What is the correct statistical test to test the
hypothesis?
Mean ± SD
1.1318 +0.16191
1.2828 +0.11039
Let F < 0.554 and F > 1.807 be the areas of rejection in the F test of two
variances [using R's qf(0.025, 71, 27) and qf(0975, 27, 71)]
