Breyers is a major producer of ice cream and would like to test the hypothesis that the average American consumes more than 17 ounces if ice cream per month. A random sample of 15 Americans was found to consume an average of 18.2 ounces of ice cream last month. The standard deviation for this sample was 3.9 ounces. Breyers would like to set
α = 0.10. Which one of the following statements is true?
▸ Because the
p-value is greater than
α, we reject the null hypothesis and conclude that the average amount of ice cream consumed per month is greater than 17 ounces.
▸ Because the
p-value is greater than
α, we fail to reject the null hypothesis and cannot conclude that the average amount of ice cream consumed per month is greater than 17 ounces.
▸ Because the
p-value is less than
α, we fail to reject the null hypothesis and conclude that the average amount of ice cream consumed per month is greater than 17 ounces.
▸ Because the
p-value is less than
α, we reject the null hypothesis and conclude that the average amount of ice cream consumed per month is less than 17 ounces.
