Question
For the accompanying data set, (a) draw a scatter diagram of the data, (b) compute the correlation coefficient, and (c) determine whether there is a linear relation between x and y. LOADING... Click the icon to view the data set. LOADING... Click the icon to view the critical values table. (a) Draw a scatter diagram of the data. Choose the correct graph below. A. 010010xy A scatter diagram has a horizontal x-axis labeled from 0 to 10 in increments of 1 and a vertical y-axis labeled from 0 to 10 in increments of 1. The following 5 points are plotted, listed here from left to right: (2, 8); (6, 2); (6, 6); (7, 4); (9, 5). B. 010010xy A scatter diagram has a horizontal x-axis labeled from 0 to 10 in increments of 1 and a vertical y-axis labeled from 0 to 10 in increments of 1. The following 5 points are plotted, listed here from left to right: (2, 8); (6, 2); (6, 6); (7, 9); (9, 5). Your answer is correct. C. 010010xy A scatter diagram has a horizontal x-axis labeled from 0 to 10 in increments of 1 and a vertical y-axis labeled from 0 to 10 in increments of 1. The following 5 points are plotted, listed here from left to right: (2, 2); (6, 4); (6, 8); (7, 1); (9, 5). D. 010010xy A scatter diagram has a horizontal x-axis labeled from 0 to 10 in increments of 1 and a vertical y-axis labeled from 0 to 10 in increments of 1. The following 5 points are plotted, listed here from left to right: (2, 2); (6, 4); (6, 8); (7, 6); (9, 5). (b) Compute the correlation coefficient. The correlation coefficient is requals nothing. (Round to three decimal places as needed.)
Explanation / Answer
The given points are:
(2, 8); (6, 2); (6, 6); (7, 9); (9, 5)
The statistical software output for this problem is:
Correlation between x and y is:
-0.28644595
Hence,
Correlation coefficient = -0.286
