# Statdisk Notes for Activity 10

## Finding the test statistic and p-value (Questions 8, 9, 19, and 20)

Find the test statistic by hand using the table, use this as a check.

- Enter the observed frequencies into column 1
- Choose Analysis / Multinomial Experiments / Equal Expected Frequencies
- Click Evaluate

The test statistic, critical value, and p-value are given. The contents of the table used to find the values are not.

## Finding the p-value without making the table (Questions 9 & 20)

The chi-square goodness of fit test is a right tail test, so the p-value is the area to the right of the test statistic.

- Choose Analysis / Probability Distributions / Chi-square distribution
- Enter the degrees of freedom
- Enter the test statistic for the Chi Sq Value
- Leave the area to the right of the chi-sq value blank since that's what we're trying to find
- Click Evaluate
