A company is started by four friends. The company was Because the P-value is less than 0.05, Erica rejects the Erica's idea, so she wants to fill 70% of the orders. Jen, null hypothesis. Because the null hypothesis is rejected, she would like to know which term contributed the significance of the test. Complete a follow-up analysis. Which term contributed the most to the significance of this test? Were there more or fewer orders being filled by this person than expected? Heather, and Tonya each agree to fill 10% of the orders. After a successful first year, Erica wants to determine if the distribution of the number of orders filled is adhering to the agreed-upon percentages. She decides to test: O Erica, more than expected Ho: PErica =0.7, Pjen =0.1, PHeather =0.1, PTonya = 0.1 H: Not all of the pi's are as stated. O Erica, fewer than expected To do so, she selects a random sample of 100 orders O Jen, more than expected from the large number of orders that were filled and O Jen, fewer than expected determines who filled the order. 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 x? = 11.20 and the P-value is between 0.01 and 0.02.
