Test the claim that a population mean is more than 16. A random sample size 24 yields = 16.09. Use a
= 0.10, and assume that Ơ = 1.4.
1. The population distribution requirement for this test is:
O None sincen > 30
O Need a normally distributed population since n <. 30
O None since this is a Z-test
O Need a normally distributed population since this is a T-test
The hypotheses are:
O Ho:p< 16; Ha:p > 16
О Но:р > 16; На:р < 16
O Ho:µ = 16; Ha:µ # 16
Ο Ho: μ <16; Ha:μ > 16
O Ho:p= 16; Ha:p 16
O Ho:µ > 16; Ha:µ < 16
2. This is a O twoO leftO right tailed test and the distribution used is
OT since o not known
OZ since ơ known
O Z since testing a proportion
The Degrees of Freedom are
ON/A; this is a Z-test
O 23
O 24

3. The STS (round to 3 decimals) is:
The P-value (round to 4 decimals) is:
4. The decision at a = 0.10 is:
O Do not reject Ho since P > a
O Reject Ho since P > a
Do not reject Ho since P < a
O Reject Ho since P < a
The conclusion is:
O There is sufficient evidence to reject the claim that the popuation mean is more than 16
O There is insufficient evidence to reject the claim that the population mean is more than 16
O There is sufficient evidence to support the claim that the population mean is more than 16
O There is insufficient evidence to support the claim that the population mean is more than 16
