(c) Use a calculator to verify that . `x = 5805, x² = 5,621,655, v = 560, y? = 61,492 and xy = 535,058. Compute r. As x increases, does the value of r imply that y should tend to increase or decrease? Explain your answer. First, we construct a computation table so that we can calculate the values of x², y', and xy. Then we sum each column to compute each summation. y v2 ху 1004 1600 40,160 97,500 64,480 135,575 40 1,008,016 950,625 984,064 874,225 975 100 10,000 4225 992 65 935 145 21,025 978 69 956,484 4,761 921 141 848,241 19,881 129,861 Σ Ex² = x = 5805 Sy = 560 xy =
