D IV. ANOVA TEST (10 points) Three machines produce products with some defects. One business manager in the manufacturing department wants to know if any one machine produces more or fewer defects than the others, because if so then he will have to take action to fix it, LOTS 32 Here are samples of the number of defects per day: Machine A produced 3, 6, 6, 3 defects across 4 days. Machine B produced 5, 5, 5, 2 defects across 4 days. mic Integrity Machine C produced 6, 5, 100 defects across 3 days.

An ANOVA test at 5% significance level applied to the samples results in this ANOVA table. source of sum squared df variation mean squares between 2322.43 2 1161.22 1.55613 groups within groups 5969.75 8 746.219 None total 8292.18 10 None None D Question 29 1 pts The number of samples (c) is 3 D Question 30 1 pts The number of data items (n) is 10 DD Question 31 2 pts The multi-sample f is 1.5561
