2. Which of the following encompasses an
“claim” involved in a hypotheses test.

b. 19
c. 38
d. 39
19. An equiprobable approach goodness of fit
test with 8 cells for data that is normally

and a std of 2, would have how many degrees of
freedom for the critical value?
a. 5
b. 6
c. 7
d. 8
20. Assuming normality and independence, if n1
or n2 or both are <30 if you cannot reject the Ho

b. chi-squared test
c. Smith-Satterthwaite test
d. paired t-test
24. Assuming normality, to determine which
comparison of means test to use, you must first
run an F test. For this test the Ho: is the variances
are the same. The Ha: is the variances are not the
same. At an alpha level of 0.10 what is your
decision?
a. Cannot reject Ho
b. Reject Ho
c. I need to retake this course
