Exhibit 1

Before finalizing the design of a keyboard, an electronics company decided to conduct an experiment to see the effect of two design choices (backlight: red vs. blue; product weight: heavy vs. light) on customers' attitude towards the product (measured on a scale of 1 to 7). Run the appropriate statistical test and at .05 level identify whether these design choices have an effect on consumers' attitude towards the product. Identify if there is a significant interaction effect (at .05 level).

Which of the following is the dependent variable in this experiment?

Select one:

a. backlight color

b. product weight

c. attitude towards the product

d. none of the other choices is correct

Refer to exhibit 1. Is there a main effect of product weight on consumers' attitude towards the product (at a significance level of .05)?

Select one:

a. Yes, product weight has a significant main effect

b. No, product weight does not have a significant effect

c. Not enough information to reach a conclusion

Exhibit 2

A retailer wants to know if the amount of sales (in $) is affected by time of the day (morning vs. afternoon) and the method customers use to place an order (online vs. phone). Run the appropriate statistical test and at .05 level identify whether these factors have an effect on the sales amount. Identify if there is a significant interaction effect (at .05 level).

Which of the following is the dependent variable in this experiment?

Select one:

a. order time

b. order method

c. amount of sales (in $)

d. none of the other choices is correct
