A manufacturer claims that the mean amount of juice in its 16 ounce bottles is 16.1 ounces.
A manufacturer claims that the mean amount of juice in its 16 ounce bottles is 16.1 ounces. A consumer advocacy group wants to perform a hypothesis test to determine whether the mean amount is actually less than this. The mean volume of juice for a random sample of 70 bottles was 15.94 ounces. Do the data provide sufficient evidence to conclude that the mean amount of juice for all 16-ounce bottles, µ, is less than 16.1 ounces? Perform the appropriate hypothesis test using a significance level of 0.10. Assume that s = 0.9 ounces.
Question 9 options:
The z of -1.49 provides sufficient evidence to conclude that the mean amount of juice is less than 16.1 oz.
The z of -1.49 does not provide sufficient evidence to conclude that the mean amount of juice is less than 16.1 oz.
The z of -0.1778 does not provide sufficient evidence to conclude that the mean amount of juice is less than 16.1 oz.
The z of -0.1778 provides sufficient evidence to conclude that the mean amount of juice is less than 16.1 oz.
