The following data was collected to explore how the number of square feet in a house, the number of bedrooms, and the age of the house affect the selling price of the house. The dependent variable is the selling price of the house, the first independent variable (x1) is the square footage, the second independent variable (x2) is the number of bedrooms, and the third independent variable (x3) is the age of the house.

Twenty five right-handed students were asked to turn a knob (using their right hands) that moved an indicator by screw action. There were two identical instruments, one with a right-hand thread (the knob turns clockwise) and the other with a left-hand thread (the knob turns counterclockwise). The data presented below gives the times (in seconds) each subject took to move the indicator a fixed distance: Obs. # R 1 2 13 14 15 6 113 105 130 101 138 118 87 IL Obs. #R 137 18 105 9 133 10 108 11 115 12 170 13 103 14 IL |Obs. # |R 116 145 15 118 75 78 16 103 96 107 17 |111 123 122 184 18 104 135 103 148 19 111 112 | 116 147 120 89 193 107 187 121 178 176 1.

The Quick Sell car dealership has been using 1-minute spot ads on a local TV station. The ads always occur during the evening hours and advertise the different models and price ranges of cars on the lot that week. During a 10-week period, the Quick Sell dealer kept a weekly record of the number x of TV ads versus the number y of cars sold. The results are given in Table below. .

A common measure of flexibility is the sit-and-reach test, where a person sits on the floor with legs straight in front. The person then reaches as far forward as possible, and the distance reached past the feet is recorded. The histograms summarize the results of the sit-and-reach test for two groups, young adult men and middle-aged men. Negative distances represent a reach that is not as far as the feet. Young Adult Men 25T 20- 15 Frequency 10- 5+ 0- -20 -10 0 10 Distance (centimeters) 20 30 Middle-Aged Men 25 20- 15- Frequency 10+ 5 -20 -10 10 20 30 Distance (centimeters) (A) (B) (C) (D) Which of the following statements is the best description of the distributions of distances?
