5. Α ____________ compares the observed frequencies from a multinomial experiment with 

        expected frequencies derived from a certain pattern or theoretical distribution. The test

         evaluates how well the observed frequencies fit the expected frequencies.

A.    Goodness-of-fit test

B.     Chi-square test

C.     Linear regression

 

6.  The __________ are the frequencies obtained from the performance of a

          if the null hypothesis is true.

A.    Observed frequencies

B.     Expected frequencies

C.     Fluctuating frequencies

 

7. The expected frequency of a category is given by Ε = np where n is the sample size and p is the

I really appreciate the work all your amazing writers do to ensure that my papers are always delivered on time and always of the highest quality.
