Cindy Ho, VP of Finance at Discrete Components, Inc. (DCI), theorizes that the discount level offered to credit customers affects the average collection period on credit sales. Accordingly, she has designed an experiment to test her theory using four sales discount rates (0%, 2%, 4%, and 6%) by randomly assigning five customers to each sales discount rate. An analysis of Cindy's data produced the following ANOVA table.

Source of Variation	SS	df	MS	F
Treatment	1844.2	3	614.7333	7.568277
Error	1299.6	16	81.225
Total	3143.8	19

Based on these results, using a 5% significance level __________

There is insufficient evidence to conclude that the average collection period on credit sales is not the same for the different discount levels.

There is insufficient evidence to conclude that credit sales increase depending on the discount levels offered.
