An ice cream supplier has recorded some sales data. Were x shows relationship between temperature Y is sales Sum x = 210 Sum y = 187 Sum x2 = 4634 Sum y2 = 3865 Sum xy = 4208 What is correlation coefficient and sales (to two decimal places)? I got coefficient 0.98 But how do I calculate sales?
As for calculating sales, the information provided I don’t think the question has enough information to calculate sales. Also I don’t think it’s a PM standard question.
