A Producer of Fine Chocolates Believes That the Sales of Two

question 81

Multiple Choice

A producer of fine chocolates believes that the sales of two varieties of truffles differ significantly during the holiday season. The first variety is milk chocolate while the second is milk chocolate filled with mint. It is reasonable to assume that truffle sales are normally distributed with unknown but equal population variances. Two independent samples of 18 observations each are collected for the holiday period. A sample mean of 12 million milk chocolate truffles sold with a sample standard deviation of 2.5 million. A sample mean of 13.5 million truffles filled with mint sold with a sample standard deviation of 2.3 million. Use milk chocolate as population 1 and mint chocolate as population 2. Which of the following is the appropriate decision given a 5% level of significance?

• A) Conclude that the average milk chocolate and mint chocolate sales differ because the p-value is greater than 0.05.
• B) Conclude that the average milk chocolate and mint chocolate sales do not differ because the p-value is less than 0.05.
• C) Do not conclude that the average milk chocolate and mint chocolate sales differ because the p-value is greater than 0.05.
• D) Do not conclude that the average milk chocolate and mint chocolate sales do not differ because the p-value is less than 0.05.

Definitions:

Intense Stimuli

Stimuli that are particularly strong or powerful, often eliciting a significant response from an organism.

Weaker Stimuli

Stimuli that have less intensity or strength, potentially producing less pronounced responses in perceptual or physiological processes.

Habituation

A decrease in response to a stimulus after being repeatedly exposed to it, showing a form of non-associative learning.

Sensitization

Sensitization is an increase in the behavioral response following repeated exposure to a stimulus, making an organism more sensitive to that stimulus over time.
