Multiple Choice

A test is made of $H _ { 0 } : \mu = 43$ versus $H _ { 1 } : \mu > 43$ . A sample of size n=76 is drawn, and $\bar { x } = 47$ . The population standard deviation is $\sigma = 25$ . Compute the value of the test statistic z and determine if $H _ { 0 }$ is rejected at the $\alpha = 0.05$ level.

• A) 0.16, H₀ rejected
• B) 1.39, H₀ rejected
• C) 1.39, H₀ not rejected
• D) 0.16, H₀ not rejected
