Question: Suppose your class is investigating the weights of Snickers 1-ounce fun-size candy bars to see if customers are getting full value for their money. Assume that the weights are normally distributed with a population standard deviation σ = 0.005 ounces. Several candy bars are randomly selected and weighed with sensitive balances borrowed from the physics lab. The weights are:

0.95 1.02 0.98 0.97 1.05 1.01 0.98 1.00

Ounces. We want to determine a 90% confidence interval for the true mean, μ.

  1. What is the sample mean?
  2. Explain the meaning of the confidence interval.
  3. Determine the z-value. Explain in detail how you knew to use a z-value for this question?
  4. Find the margin of error.
  5. Determine the 90% confidence interval for the mean weight of the candy bars.
