Score: 0.29 of 1 pt 6 of 16 (15 complete) HW Score: 85.54%, 13.69 of 16 pi (%) 4.1.17 Question Help Data set re is a linear For the accompanying data set, (a) draw a scatter diagram of the relation between x and y whether the Click here to view the data set Click her 4 7 19 view ritical values table 4 12 14 10 10 10 Print Done (b) By hand, compute the correlation coefficient. The correlation coefficient is r.96. (Round to three decimal places as needed.) (c) Determine whether there is a linear relation between x and y Because the correlation coefficient is and the absolute value of the correlation coefficient,, is than the critical value for this data set, linear relation exists between x and y (Round to three decimal places as needed.)

Explanation / Answer

Ans:

a)

Correlation cofficient=0.960

b)n=5

df=5-2=3

critical r value(two tailed)=0.878

absolute value of sample correlation cofficient=0.960

As,absolute value of sample correlation cofficient is greater than critical r value(0.878),so there is significant linear relation exists between x and y.
