Question

Dr. Snycerski computed a confidence interval for the mean number of alcoholic beverages consumed per week in a random sample of US college students. The 95% confidence interval is 3 to 6. What does this confidence interval tell us about the mean number of alcoholic beverages consumed per week by the population of all US college students

Answer 1

Answer:

We are 95% sure that the true mean number of alcoholic beverages consumed per week by the population of all US college students is between 3 and 6.

Step-by-step explanation:

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

In this question:

95% confidence interval is between 3 and 6.

This means that we are 95% sure that the true mean number of alcoholic beverages consumed per week by the population of all US college students is between 3 and 6.
