She finds that Erica filled 56 orders, Jen filled 18, Heather filled 14, and Tonya filled 12. The chi-square test statistic for goodness of fit is x² = 11.20 and the P-value is between 0.01 and 0.02. Because the P-value is less than 0.05 Erica rejects the null hypothesis. She completes a follow-up analysis.
