A linear correlation coefficient is a number calculated from given data that measures the strength of the linear relationship between two variables: x and y. The sign of the linear correlation coefficient indicates the direction of the linear relationship between x and y.
Compute the standardized value of each yi using the formula (zy)i = (yi – ş) / s y . Assemble the product from the last step. Divide the previous step sum by n - 1. where n is the total number of points in the paired data set. All these results have a correlation coefficient of r
. The correlation coefficient formula indicates how close the linear relationship is between two variables. R-squared is the square of the correlation coefficient r (hence the formula r-squared).

Each number is the previous number plus 5 ( 8 + 5 = 13, 13 + 5 = 18), so the next item would be 18 + 5 = 23
Let's say that the shorter piece is x and the longer piece is 5x (because it's 5 times as long). x+5x=72 and 6x=72. Dividing both sides by 6, we get that x=12, and 72-12=the length of the other piece (since there are only 2 pieces)=60
Answer: I would say because he choose 5 for each in stead of just choosing 5 period for both of them so they can listen to both instead of just having 5 listening to CLASSIC and a different 5 listening to OCEAN music, another problem is the amount of people he choose is uneven it should be even so that if it is 5 well there wasnt another student to change it if it is even then there could be like 3 for OCEAN music and maybe 2 for CLASSIC music if it ends out 3 for both just add 2 more kids.
