An SRS of 30 properties recently sold in a midwestern city was taken. The scatter plot below show the actual sales prices and the assessed values of the 30 properties. Both variables are measured in 8 250- 200- thousands of dollars. 150- Let y; and x; be respectively the sales price and the assessed value of the ith property.
