Question

Suppose that a company claims that its chocolate bars weigh 3.2 ounces on average. The company took many large samples, and each time the mean weight of the sample was within 95% of the confidence interval. Which of the following would be a reasonable conclusion?

A. The company's chocolate bars weigh 3.2 ounces on average
B. The company's chocolate bars weigh more than 3.2 ounces on average
C. The company's chocolate bars weigh fewer than 3.2 ounces on average
D. The company's chocolate bars do not weigh 3.2 ounces on average.

Answer 1

if the population mean truly is 3.2 ounces, you expect sample means to fall within the confidence interval 95% of the time

Answer 2

yea i figured the mean would be the same so on average the company's chocolate bars should still weigh the same (3.2 ounces) but I just wanted to double check

Answer 3

Answer 4
