The following data show the educational level and productivity of 20 employees in the City of Fullerton Social Services Agency. Set up a contingency table on education and productivity and analyze your table to explain if there is a relationship between employee education and productivity. Education: SC = some college, BA = bachelor’s, MA = master’s Productivity = number of cases completed per week by the employeeSuppose Ted is creating a football team in a video game that features many NFL players. He decides to identify players who are outliers in a few statistics he has chosen. Currently, he's looking at wide receivers. The game includes the top 100 receivers in 2012 by number of receptions. Ted, however, is more interested in receiving yards, and the table shows the five-number summary of the available players in the game (in yards): Minimum 1st quartile (Q1) Median 3rd quartile (Q3) Maximum 258.0 549.5 743.0 936.5 1964.0 The mean is 787.6 yds with a standard deviation of 311.3 yds. Ted first calculates the interquartile range (IQR). Next, to determine suspected outliers, he calculates Q1−1.5⋅???Q1−1.5⋅IQR and Q3+1.5⋅???Q3+1.5⋅IQR. Specify those results to at least one decimal place. Q1−1.5⋅???Q1−1.5⋅IQR = Q3+1.5⋅???Q3+1.5⋅IQR =
