You may need to use the appropriatetechnologyto answer this question. In 2018, a consumer goods giant had more than 20 brands with more than $1 billion in annual sales. How does the company create so many successful consumer products? They effectively invest in research and development to understand what consumers want. One method used to determine consumer preferences is called conjoint analysis. The conjoint analysis allows a company to ascertain the utility that a respondent in the conjoint study places on a design of a given product. The higher the utility, the more valuable a respondent finds the design. Suppose we have conducted a conjoint study and have the following estimated utilities (higher is preferred) for each of three different designs for a new whitening toothpaste.

Respondent Utilities
Design A Design B Design C
1 24.6 34.8 28.4
2 31.4 31.8 33.5
3 31.8 20.6 27.4
4 15.4 26.8 24.7
5 20.7 18.7 17.8
6 41.0 34.4 44.4
7 27.1 22.9 26.9
8 20.2 22.2 27.5
9 31.6 29.8 30.9
10 24.4 29.4 28.9

At the 0.05 level of significance, test for any significant differences. State the null and alternative hypotheses.

H0:Design A=Design B=Design C Ha: Not all the population means are equal.H0: Not all the population means are equal. Ha:Design A=Design B=Design C H0: At least two of the population means are equal. Ha: At least two of the population means are different.H0:Design ADesign BDesign C Ha:Design A=Design B=Design CH0:Design A=Design B=Design C Ha:Design ADesign BDesign C

Find the value of the test statistic. (Round your answer to two decimal places.)

Find thep-value. (Round your answer to three decimal places.)p-value =

State your conclusion.

RejectH0. There is sufficient evidence to conclude that there is a difference in design.

Do not rejectH0. There is not sufficient evidence to conclude that there is a difference in design.

RejectH0. There is not sufficient evidence to conclude that there is a difference in design.

Do not rejectH0. There is sufficient evidence to conclude that there is a difference in design.
