Statistics question side

words:

Imagine you are a product manager at Chips Amor Cookie Company and you want to test how accurate the claim is that your cookies have more chocolate chips than the those produced by a local grocery store brand.

To do this, you gather a team of consumers to compare the cookies. You give each participant a Chips Amor cookie in a bag labeled A and a local grocery store brand cookie in a bag labeled B. They are asked to count the number chips in each cookie. You have 30 participants.

• What parameters would they be comparing?
• How can you write a null hypothesis and an alternative hypothesis?
• What are the populations from which the samples came?
• Based on your hypothesis, is this a one-tailed or two-tailed test?

Write a null hypothesis and a research hypothesis:

• So, are the samples of cookies random?
• Are the two samples independent of each other?
