we have to find the sample correlation coefficient for this data to obtain the relation between pair of variable
r = 0.91873
Figure 4
Since correlation coefficient between u and v is r = 0.91873 Then the sample correlation coefficient r closest to 1
Ans :
1. For which data set is the sample correlation coefficient r closest to 0 | data set (x,y) |
2.For which data set is the sample correlation coefficient r closest to -1 |
data set (u,v) and data set (w,t) |
3) For which data set is the sample correlation coefficient r closest to 1 | data set (m,n ) |
4) which data set indicates the strongest positive linear relationship between its two variables | data set (m,n ) |

The distribution for a population of measurements is presented in the histogram below. The mean is 3.2 and the standard deviation is 2. Suppose that five students each take a sample of ten values from the population and each student calculates the sample mean for his or her ten data values. The students draw a dotplot of their five sample means on the classroom board so that they can compare them. Which of the dotplots a -c do you think...
