Solution

the hypothesis test is

The total sale amounts for each entire marking period (start, end) is a population. A= 0.05

nujll hypothesis is :Angles=prooofs=triangles

Alternative hypothesis :there is difference between total sales amount.

reject null hypothesis. 0.05

The numbers are not equal

hence ascending order is Angles,prooofs, triangles.
