Step-by-step explanation:

Mean of the origibal set = 20

No. of terms = 10

Sum = Mean x No. of terms

New Mean = New Sum/ N

= 420/10

Hence we created a relationship between y and x , or in English, between the earning and the number of hours worked.
Moreover y depends on x, if  there is no x, there is no y and if x increases, y increases. However x is an INDEPENDENT variable because you can
give to x any number & y will follow
