Commute Time (in minutes) Well-Being Score 6 69.9 14 68.4 26 67.6 34 67.1 47 66.5 73 65.2 105 63.5 (a) Which variable is likely the explanatory variable and which is the response variable? A. The explanatory variable is commute time and the response variable is the well-being score because well-being score affects the commute time score. B. The explanatory variable is the well-being score and the response variable is commute time because commute time affects the well-being score. C. The explanatory variable is the well-being score and the response variable is commute time because well-being score affects the commute time. D. The explanatory variable is commute time and the response variable is the well-being score because commute time affects the well-being score. Your answer is correct. (b) Draw a scatter diagram of the data. Which of the following represents the data? A. 60700110Commute Time (min)Score A scatter diagram has a horizontal axis labeled “Commute Time (minutes)” from 60 to 70 in increments of 1 and a vertical axis labeled “Score” from 0 to 110 in increments of 10. The following 7 approximate points are plotted, listed here from left to right: (63.6, 106); (65.2, 74); (66.6, 48); (67.2, 34); (67.6, 26); (68.4, 14); (70.0, 6). The points follow the general pattern of a straight line that falls from left to right. B. 01106070Commute Time (min)Score A scatter diagram has a horizontal axis labeled “Commute Time (minutes)” from 0 to 110 in increments of 10 and a vertical axis labeled “Score” from 60 to 70 in increments of 1. The following 7 approximate points are plotted, listed here from left to right: (6, 70.0); (14, 68.4); (26, 67.6); (34, 67.2); (48, 66.6); (74, 65.2); (106, 63.6). The points follow the general pattern of a straight line that falls from left to right. Your answer is correct. C. 01106070Commute Time (min)Score A scatter diagram has a horizontal axis labeled “Commute Time (minutes)” from 0 to 110 in increments of 10 and a vertical axis labeled “Score” from 60 to 70 in increments of 1. The following 7 approximate points are plotted, listed here from left to right: (6, 63.6); (14, 65.2); (26, 66.6); (34, 67.2); (48, 67.6); (74, 68.4); (106, 70.0). The points follow the general pattern of a curve that rises from left to right at a decreasing rate. D. 01106070Commute Time (min)Score A scatter diagram has a horizontal axis labeled “Commute Time (minutes)” from 0 to 110 in increments of 10 and a vertical axis labeled “Score” from 60 to 70 in increments of 1. The following 7 approximate points are plotted, listed here from left to right: (6, 63.6); (14, 70.0); (26, 65.2); (34, 68.4); (48, 66.6); (74, 67.6); (106, 67.2). The vertical spread of the points decreases from left to right. (c) Determine the linear correlation coefficient between commute time and well-being score. requals nothing (Round to three decimal places as needed.)
Commute time is increasing as Well being score decreases hence
Well being score is independent and Commute time is dependent
Response variable=Commute time
Explanatory variable= Well Being score
hence option C
corelation coefficient=0.194187
=0.194
using excel correl() function we get 0.194

The scatter plots below show the results of a survey of 20 randomly selected males ages 24dash–35. Using age as the explanatory variable, match each graph with the appropriate description. A scatter plot has a horizontal x-axis labeled Age from 24 to 36 in increments of 2 and a vertical y-axis labeled In thousands of units from 0 to 100 in increments of 20. Twenty plotted points with integer horizontal coordinates follow a general pattern of rising from left to...
