A Marketing Researcher Was Studying the Effect of a Supermarket

question 15

Multiple Choice

A marketing researcher was studying the effect of a supermarket display on sales of a new product. There were two designs for the display: the first had greater visual appeal and the second contained more factual information about the product. Each type of display could be made in three sizes: small, medium, or large. Eighteen supermarkets were available for the study, and three supermarkets were selected at random to display each combination of design and size. The number of units of the product sold over a two-week period was recorded for each supermarket. For the resulting data, a two-way ANOVA was run, with the partial ANOVA table given below. Analysis of variance for sales: What conclusion should be drawn from this test?

• A)Accept the null hypothesis.
• B)Fail to reject the null hypothesis-there is no evidence to suggest that design is more or less likely to influence sales.
• C)Reject the null hypothesis-there is some evidence that design influences sales.
• D)Reject the null hypothesis-there is strong evidence that design influences sales.
