The following data is the average age of five randomly selected workers at each plant. The data and the partial results of a one-way ANOVA table are listed below: Employees' Ages (in Yea rs} N = 15 7c = 23.33 n; = 5 2 = 32.0 Source of Va riance Between Within Total 1.

He records the number of defective parts made by the three assembly lines each day over the course of a week.

To test their claim, they record the number of calls received during each shift for seven days. Based on this data, can the paramedics conclude that the average number of calls is different between shifts?
