The calculator at this link will allow you to perform a one-way chi-square or “goodness of fit test”: http://vassarstats.net/csfit.html. Fifty students can choose between four different professors to take Introductory Statistics. The number choosing each professor is shown below. Use the calculator above to test the null hypothesis that there is no preference for professors -- that there is an equal chance of choosing each of them. Report your results including chi-square, degrees of freedom, p-value and your interpretation. Use an alpha level of .05. Be careful not to over interpret – state only what the test result tells you.
Professor N
Dr. Able 20
Dr. Baker 8
Dr. Chavez 14
Dr. Davis 8

as per given instruction i have performed the chi square test.
the findings are as followed:-
interpretation:
p value=0.0477<0.05, so,we have enough evidence to reject our null hypothesis.
so,here is not sufficient evidence to claim the null hypothesis,i.e, there is no preference for professors -- that there is an equal chance of choosing each of them.
***if you have any doubt regarding the problem please write it in the comment box.if you are satisfied please give me a LIKE if possible

For each of the following examples, state whether the chi-square
goodness-of-fit test or the chi-square test for independence is
appropriate, and state the degrees of freedom (df) for the
test.
Part A) An instructor tests whether class attendance (low, high)
and grade point average (low, average, high) are independent.
- State whether the chi-square goodness-of-fit test or the
chi-square test for independence is appropriate.

chi square goodness of fit test
Epistasis is a phenomenon in which one gene controls the
expression of another. In one case, a dihybrid cross should yield a
9:3:4 ratio. You collect the following data on mice: black coat: 69
brown coat: 23 white coat: 30 Is there any reason to doubt the
ratio of 9 black : 3 brown : 4 white?
