Question
Test the claim that a population mean salary in a town is more than $62000. A random sample of 24
salaries yields = $62171.46 and s = $1400. Use a = 0.10.
1. The population distribution requirement for this test is:
O Need a normally distributed population since this is a T-test
O Need a normally distributed population since n < 30
O None since n> 30
O None since this is a Z-test
Coa
The hypotheses are:
O Ho:p > 62000; Ha:p < 62000
Ho:u > 62000; Ha:u < 62000
O Ho:µ < 62000; Ha:µ > 62000
O Ho:p = 62000; Ha:p + 62000
O Ho: u = 62000; Ha:µ 62000
O Ho:p< 62000; Ha:p > 62000
2. This is a O twoO rightO left tailed test and the distribution used is
OT since o not known
OZ since testing a proportion
Oz since o known
The Degrees of Freedom are
O 23
ON/A; this is a Z-test
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 Reject Ho since P< a
O Do not reject Ho since P > a
O Do not reject Ho since P<a
O Reject Ho since P > a
The conclusion is:
O There is sufficient evidence to support the claim that the population mean salary is more than
$62000
O There is insufficient evidence to reject the claim that the population mean salary is more than
$62000
O There is insufficient evidence to support the claim that the population mean salary is more than
$62000
O There is sufficient evidence to reject the claim that the popuation mean salary is more than $62000
