Question 12 Test the claim that a population mean is different than 18. A random sample of 30 values yields x = 17.89 and s = 1.5. Use a = 0. 10. 1. The population distribution requirement for this test is: O Need a normally distributed population since n 18 O Ho:u 18 O Ho:p = 18; Ha:p # 18 O Ho:u 2 18; Ha:p a: '72:? Do not reject Ho since P E? a: 5:33 Reject Ho since P :3 a '5'} Reject Ho since P E a The conclusion is: ""33 There is sufficient evidence to reject the claim that the popuation mean is different than 18 ""3 There is sufficient evidence to support the claim that the population mean is different than 18 ""3? There is insufficient evidence to support the claim that the population mean is different than 18 513' There is insufficient evidence to reject the claim that the population mean is different than 18
