Hypotheses for Chi-Square Goodness-of-Fit Test

For a chi-square goodness-of-fit test, the hypotheses are as follows:

H₀: The population proportions in each category are consistent with the specified values in each category.
H₁: The population proportions in each category are not consistent with the specified values in each category.

You can test equal proportions, specified proportions, or proportions based on historical data.
