The data in the table to the right are based on the results of a survey comparing the commute time of adults to their score on a well-being test. Draw a scatter diagram of the data. Does a linear relation exist between the commute time and well-being index score, when the linear correlation coefficient is -0.991? Commute Time (in minutes) Well-Being Score 4 69.2 16 68.9 23 67.9 34 67.7 53 66.3 74 65.2 95 63.1.

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....
2. The data in the table to the right are based on the results of a survey comparing the commute time of adults to their score on a well-being test. Determine the linear correlation coefficient between commute time and well-being score. Round your answer to three decimal places.

Assigned Media Question Help Researchers initiated a long-term study of the population of American black bears. One aspect of the study was to develop a model that could be used to predict a bear's weight (since it is not practical to weigh bears in the field). One variable thought to be related to weight is the length of the bear. The accompanying data represent the lengths and weights of 12 American black bears. Complete parts (a) through (d) below. Click...
The accompanying data represent the total compensation for 12 randomly selected chief executive officers (CEO) and the company's stock performance in a recent year. Complete parts (a) through (d) below. Click the icon to view the CEO data. (a) One would think that a higher stock return would lead to a higher compensation. Based on this, what would likely be the explanatory variable? Stock return Compensation (b) Draw a scatter diagram of the data. Use the result from part (a)...
