In a goodness-of-fit test, suppose that a sample showed that the observed frequency and expected frequency were equal for each cell i. Then, the null hypothesis is:

A) rejected at0.05 but is not rejected at0.025
B) not rejected at0.05 but is rejected at0.025
C) rejected at any level
D) not rejected at anylevel
E) not rejected at> 0.05

Null Hypothesis

A hypothesis used in statistical testing that assumes no significant difference or effect exists between certain states or variables.

Observed Frequency

The number of times a particular value or category of data occurs in a set of data, used in the analysis of categorical variables.

Expected Frequency

The theoretically calculated frequency of an event or outcome based on the probabilities in a statistical experiment, often compared to observed frequencies in chi-squared tests.
