Question: This table contains the cost per ounce ($USD) for a sample of 14 dark chocolate bars Construct a 99% Confidence Interval estimate for the population

  1. This table contains the cost per ounce ($USD) for a sample of 14 dark chocolate bars

  1. Construct a 99% Confidence Interval estimate for the population cost per ounce of dark chocolate bars. (Have to find the sample mean and standard deviation first; sample meanbecomes your point estimate)
  2. Construct a 95% confidence interval estimate using the same data.
  3. Which estimate gives the larger range of data?
