In order for a candy company to claim that a bridge mix is mostly chocolate stars, a proportion of at least 0.8 of the packages must contain 3 ounces or more of chocolate stars. Quality control tests a random sample of 50 packages to determine if the proportion is less than 0.8 at a significance level of 0.05. Use Sheet 5 of the Excel file to calculate p^, the z-score, and the p-value.

p^=

z=

p=

Since the p-value is

evidence exists that the proportion of packages with 3 ounces or more of chocolate stars is less than 0.8
