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( Greater or Less) evidence than the significance level 0.05 , the null hypothesis ( fails to be rejected or is rejected)

.

( sufficient or insufficient ) evidence exists that the proportion of packages with 3

ounces or more of chocolate stars is less than 0.8
