Answer 1

Moonbucks' survey result does provide sufficient evidence to support opening a store at WLU.

Step-by-step explanation:

To determine if Moonbucks' survey result provides sufficient evidence to support opening a store at WLU, we need to compare the survey result to the claim made in McBeans magazine. According to McBeans, 80% of people at universities drink coffee regularly. In the random sample taken at WLU, 680 out of 810 participants considered themselves regular coffee drinkers.

To see if this result provides sufficient evidence, we can calculate the proportion of regular coffee drinkers in the sample. The proportion is calculated by dividing the number of regular coffee drinkers by the total number of participants:

Proportion = Number of regular coffee drinkers / Total number of participants = 680/810 = 0.839

The proportion of regular coffee drinkers in the sample is 0.839, which is greater than 80%. Therefore, Moonbucks' survey result does provide sufficient evidence to support opening a store at WLU.
