In the chi-square goodness-of-fit test, if the expected frequencies and the observed frequencies were quite different, we would conclude that the:
A) null hypothesis is false, and we would reject it
B) null hypothesis is true, and we would not reject it
C) alternative hypothesis is false, and we would reject it
D) chi-square distribution is invalid, and we would use the t-distribution instead
Null Hypothesis

Expected Frequencies
The predicted count of occurrences across different categories in a statistical analysis.
Observed Frequencies
The actual counts or occurrences of variables in a dataset, as recorded or observed without any modifications.
