Question\text{Listed in the accompanying table are weights (lb) of samples of the contents of cans of regular Coke and Diet Coke. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Complete parts (a) to (c).} \\
\text{a. Use a 0.01 significance level to test the claim that the contents of cans of regular Coke have weights with a mean that is greater than the mean for Diet Coke.} \\
\text{What are the null and alternative hypotheses? Assume that population 1 consists of regular Coke and population 2 consists of Diet Coke.} \\
\begin{itemize} \item \text{A. } H_{0}: \mu_{1} \leq \mu_{2} \quad H_{1}: \mu_{1}>\mu_{2} \item \text{B. } H_{0}: \mu_{1} \neq \mu_{2} \quad H_{1}: \mu_{1}>\mu_{2} \item \text{C. } H_{0}: \mu_{1}=\mu_{2} \item \text{D. } H_{0}: \mu_{1}=\mu_{2} \quad H_{1}: \mu_{1}>\mu_{2} \end{itemize}
\text{The test statistic is } \square \text{ (Round to two decimal places as needed.)} \\
\text{The P-value is } \square \text{ (Round to three decimal places as needed.)} \\
\text{State the conclusion for the test.} \\
\begin{itemize} \item \text{A. Reject the null hypothesis. There is not sufficient evidence to support the claim that cans of regular Coke have weights with a mean that is greater than the mean for Diet Coke.} \item \text{B. Reject the null hypothesis. There is sufficient evidence to support the claim that cans of regular Coke have weights with a mean that is greater than the mean for Diet Coke.} \item \text{C. Fail to reject the null hypothesis. There is not sufficient evidence to support the claim that cans of regular Coke have weights with a mean that is greater than the mean for Diet Coke.} \item \text{D.

Studdy Solution
State the conclusion:
- If the null hypothesis is rejected, conclude that there is sufficient evidence to support the claim that the mean weight of regular Coke is greater than that of Diet Coke. - If the null hypothesis is not rejected, conclude that there is not sufficient evidence to support the claim.
The test statistic is \square (to be calculated and rounded to two decimal places).
The P-value is \square (to be calculated and rounded to three decimal places).
Based on the P-value, choose the appropriate conclusion from the given options.
