It is thоught thаt prehistоric Nаtive Americаns did nоt take their best tools, pottery, and household items when they visited higher elevations for their summer camps. It is hypothesized that archaeological sites tend to lose their cultural identity and specific cultural affiliation as the elevation of the site increases. Let x be the elevation (in thousands of feet) for an archaeological site in the southwestern United States. Let y be the percentage of unidentified artifacts (no specific cultural affiliation) at a given elevation. Suppose that the following data were obtained for a collection of archaeological sites in New Mexico: x 5.25 5.75 6.75 7.00 8.00 y 26 56 75 86 80 Calculate the sample correlation coefficient r. Round your answer to three decimal places.

Age in Years 0-1 2 3 4 5 6 7 8 9 10 11 12 13 First Location (Number of Boys) 4 5 5 6 6 8 8 8 9 9 10 10 11 Second Location (Number of Boys) 4 5 5 6 6 7 7 7 8 8 8 8 9 Third Location (Number of Boys) 4 4 5 5 5 5 6 6 6 7 7 9 10 The data set for the first location has a normal distribution, for the second location it is skewed to the left, and for the third location it is skewed to the right. What data set has the mean value less than the median, and both the mean and the median less than the mode?
