In order to study the effect of color on the sales of cashew nuts, a company constructed two identical displays. One contained pack- ages of nuts wrapped in clear cellophane and the nuts in the other were wrapped in red cellophane. One of each was placed on oppo- site sides of the cash register.

(a) How would assign the position (L or R) at each of the six locations?
(b) The resulting sales are
Let µ =population mean wingspan in centimeters. Formulate the hypotheses when the intent of the test is to show that the sales are higher with clear wrappings.
(c) Conduct a test of hypotheses using a t - statistic. Take $\alpha$ = .05
(d) Based on the conclusion to your test in Part c, what error could you have made.
(e) Explain why this possible error will seldom occur.
