What percentage of data would you predict would be between 25 and 50 and what percentage would you predict would be more than 50 miles? Use the Week 4 spreadsheet again to find the percentage of the data set we expect to have values between 25 and 50 as well as for more than 50. Now determine the percentage of data points in the dataset that fall within each of these ranges, using same strategy as above for counting data points in the data set. How do each of these compare with your prediction and why is there a difference? Predicted percentage between 25 and 50: ________________________ Actual percentage: Predicted percentage more than 50 miles: Actual percentage: ___________________________________________ Comparison ____________________________________________________ Why? __________________________________________________________ Drive: 44 20 88 6 71 42 76 63 61 63 84 28 55 33 88 80 86 83 5 85 25 25 54 54 81 73 29 76 78…
Marco shows you the following chart to help him argue that while his division’s sales numbers aren’t as high as those of the other divisions, he’s actually not that far behind them, when you look at the data visually. How is Marco using a chart to lie to you? What would a more accurate representation of Marco’s performance look like?
Over the span of a month, a school tracks student choices at lunch. They find that 56% of all students buy milk with lunch and 32% buy a piece of fruit. If 22% of all students buy both milk and fruit, which of the following represents the percent of students who buy neither? (1) 28% (3) 42% (2) 34% (4) 46%
. Honesty Coffee stations in offices often just ask usersto leave money in a tray to pay for their coffee, butmany people cheat. Researchers at Newcastle Universityalternately taped two posters over the coffee station.During one week, it was a picture of flowers; during theother, it was a pair of staring eyes. They found that theaverage contribution was significantly higher when theeyes poster was up than when the flowers were there.Apparently, the mere feeling of being watched—even byeyes that were not real—was enough to encourage peopleto behave more honestly.

As students move away to go to college, studies show that they gain an average of 15 pounds during their freshman year when they move out of their parent’s house into a dorm or apartment. This phenomenon is known as “the freshman fifteen.” A study is conducted on a SRS of 11 freshman who moved out of their parent’s house for the first time to attend college. The study participants agreed to be weighed at the beginning and end of their freshman year. Does there appear to be enough evidence from the sample of 11 students to show that students, on average, gain weight during their freshman year? Use a = .01 and assume that both sets of data are normally distributed. Subject 1 2 3 4 5 6 7 8 9 10 11 Weight at beginning of freshman year 175 151…
Mrs. Kelso and Mr. Bonham gave each of their students a small bag of colored tiles. The students each counted the number of purple tiles they received. The box plots display the data for both classes. Purple Tiles Mrs. Kelso's class Mr. Bonham's class 10 15 20 Number of Purple Tiles Which statement is best supported by the information in the box plots? A The range of the data for Mr. Bonham's class is less than the range of the data for Mrs. Kelso's class. B The data for Mrs. Kelso's class are more symmetrical than the data for Mr. Bonham's class. C The median number of the data for Mr. Bonham's class is less than the median number of the data for Mrs. Kelso's class. D The interquartile range of the data for Mrs. Kelso's class is greater than the interquartile range of the data for Mr. Bonham's class.
