In a Two-Sample Test for Differences in Means, the Hypotheses $H_{0}: \mu_{1}-\mu_{2}\{\geq, \leq$

question 30

Multiple Choice

In a two-sample test for differences in means, the hypotheses are of the form:

• A) \( H_{0}: \mu_{1}-\mu_{2}\{\geq, \leq \), or \( =\} 0 \)
• \( H_{1}: \mu_{1}-\mu_{2}\{>,< \), or \( =\} 0 \)
• B) \( H_{0}: \mu_{1}-\mu_{2}\{\geq, \leq \), or \( =\} 0 \)
• \( H_{1}: \mu_{1}-\mu_{2}\{>,< \), or \( \neq\} 0 \)
• C) \( H_{0}: \mu 1-\mu 2\{\geq, \leq \), or \( \neq\} 0 \)
• \( H_{1}: \mu_{1}-\mu_{2}\left\{>_{1}<\right. \), or \( \left.=\right\} 0 \)
• D) \( H_{0}: \mu 1-\mu 2\{>,< \), or \( =\} 0 \)
• \( H_{1}: \mu 1-\mu 2\{\leq, \geq \), or \( \neq\} 0 \)
