A. What is the critical value for a goodness of fit test with 7 categories assuming α = 5%?
For k = 7, df = n-1 , α = 5% = 0.05
Critical value = 12.592
B. A goodness of fit test where the Ho is accepted would have a conclusion of?
When Ho is accepted in goodness of fit test then conclusion is,
The data are consistent with a specified distribution.
C. A goodness of fit test with a test statistic of 2.56 and a critical value of 3.325 would result in a conclusion of?
Here test statisitic value 2.56 is less than the critical value 3.325 hence conclusion is
Fail to reject Ho.
D. The symbol used for the test statistic in a goodness of fit test is?

You are conducting a Goodness of Fit hypothesis test for the
claim that the 4 categories occur with the following
frequencies:
H0H0 : pA=0.15pA=0.15; pB=0.3pB=0.3; pC=0.15pC=0.15;
pD=0.4pD=0.4
Give all answers as decimals rounded to 3 places after
the decimal point, if necessary.
