An online seller asks customers to rate the cellphone case that they purchased using a 1-to-5-star ratings.: the higher the number of stars, the higher the recommendation. Their ratings are given below.

Mean:

Standard Deviation: s=0.97

Suppose you decreased each rating by 1 star. Compare the new mean and standard deviation then formulate a general rule. What would you conclude regarding the degree to which the customers agree or disagree about the product?

• Most of the customers don’t agree to recommend the product; the mean increases/decreases as the star rating increases/decreases while the standard deviation remains the same.

• Most of the customers would likely agree to recommend the product; the mean increases/decreases as the star rating increases/decreases while the standard deviation remains the same.

• Most of the customers strongly agree to recommend the product; the mean increases/decreases by 1 while the standard deviation remains the same.

• Most of the customers strongly disagree to recommend the product; the mean remains the same while the standard deviation increases
