- O Attempt 2 1 of 17 Suppose 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 IQR and Q3 + 1.5 - IQR. Specify those results to at least one decimal place. 387 Q1 – 1.5 IQR = Q3+ 1.5 1QR= 1517 Incorrect Ted identified the top five receivers available in the game by the number of receiving yards.

"When a company's satisfaction score has improved over the prior year's results and is above the national average (75.6), studies show its shares have a good chance of outperforming the broad stock market in the long run." The following satisfaction scores of three companies for the 4th quarters of two previous years were obtained from an economic indicator. Assume that the scores are based on a poll of 50 customers from each company. Because the polling has been done for several years, the standard deviation can be assumed to equal 6 points in each case. Company Year 1 Year 2 Company A 73 76 Company B 75 77 Company C 77 78 (a) For Company A, is the increase in the satisfaction score from year 1 to year 2 statistically significant? Use ? = 0.05.

For her experiment, she randomly selects 15 items currently in stock and proceeds to establish a baseline. The 15 items are priced at their usual competitive values, and the quantity of each item sold for a 1-week period is recorded. Then, without changing their price, she places a large ad in the newspaper, advertising the 15 items. She records the quantity sold for a 1-week period.
