Multiple Choice

Which of the following statements are not true?

• A) If the null hypothesis is \(H _ { o } : \mu = 50 , \bar { x } = 53 \text {, and } \sigma _ { \bar { x } } = \sigma / \sqrt { n } = 1.2\)
• , then the test statistic value is t = -2.5.
• B) If the alternative hypothesis has the form \(H _ { \pm } : \mu > \mu _ { o }\)
• , then an \(\bar { x }\)
• Value less than \(\mu _ { 0 }\)
• Certainly does not provide support for \(H _ { \pm }\)
• )
• C) If the alternative hypothesis has the form \(H _ { \pm } : \mu > \mu _ { o }\)
• , then an \(\bar { x }\)
• Value that exceeds \(\mu _ { 0 }\)
• By only a small amount (corresponding to z which is positive but small) does not suggest that \(H _ { o }\)
• Should be rejected in favor of \(H _ {\pm }\)
• )
• D) All of the above statements are true.
