question 16

Multiple Choice

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 16ounce bottles, $\mu$ , is less than $16.1$ ounces? Perform the appropriate hypothesis test using a significance level of $0.10$ . Assume that $\sigma=0.9$ ounces.

• A) The \( z \) of \( -1.49 \) provides sufficient evidence to conclude that the mean amount of juice is less than \( 16.1 \mathrm{oz} \).
• B) The \( z \) of \( -1.49 \) does not provide sufficient evidence to conclude that the mean amount of juice is less than \( 16.1 \mathrm{oz} \).
• C) The \( z \) of \( -0.1778 \) does not provide sufficient evidence to conclude that the mean amount of juice is less than \( 16.1 \mathrm{oz} \).
• D) The \( z \) of \( -0.1778 \) provides sufficient evidence to conclude that the mean amount of juice is less than \( 16.1 \mathrm{oz} \). 113
