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.
