Question

A marketing executive wishes to test whether there is a difference in preference among three display designs at a 1% significance level. Can you set up the hypotheses for this problem?

Answer 1

To test the difference in preference among three display designs, the marketing executive needs to set up the null and alternative hypotheses.

Step-by-step explanation:

In this problem, the marketing executive wants to test whether there is a difference in preference among three display designs. To do this, they need to set up the null and alternative hypotheses.

The null hypothesis, denoted as H0, states that there is no difference in preference among the three display designs. The alternative hypothesis, denoted as Ha, states that there is a difference in preference among the three display designs.

The null and alternative hypotheses can be written as:

H0: The mean preference is the same for all three display designs.

Ha: The mean preference is different for at least one of the display designs.
