An association between the two variables:
=> School Play : Brand Concert = constant
=> School Play / Brand Concert = constant on Thursday and Friday
300/184 Thursday
x/250 Friday
Equate both:
300/184 = x/250
=> x = 300 x 250 /184
=> x = 407
Value of x = 407
=> School Play : Brand Concert = constant
=> School Play / Brand Concert = constant on Thursday and Friday
300/184 Thursday
x/250 Friday
Equate both:
300/184 = x/250
=> x = 300 x 250 /184
=> x = 407
Value of x = 407
