Eight randomly selected customers at a local grocery store spent the following amounts on groceries in a single visit: $214, $184, $31, $92, $148, $175, $7, and $57. Let y denote the amount spent on groceries by a single customer in a single visit. Find the following:

a. ∑y
b. (∑y)^2
c. ∑y^2

Eight randomly selected customers at a local grocery store spent the following amounts on groceries in a single visit: $214, $184, $31, $92, $148, $175, $7, and $57.

Let y denote the amount spent on groceries by a single customer in a single visit.

a. ∑y = 214 + 184 + 31 + 92 + 148 + 175 + 7 + 57 = 908

b. (∑y[tex]) ^{2}[/tex] = [tex]908^{2}[/tex] = 824464

c. ∑[tex]y^{2}[/tex] = [tex]214^{2} + 184^{2} + 31^{2} + 92^{2} + 148^{2} + 175^{2} + 7^{2} + 57^{2}[/tex] = 144904
