Question
Is the difference between the mean annual salaries of entry level architects in Denver, Colorado, and Lincoln, Nebraska, equal to $11,000? To decide, you select a random sample of entry level architects from each city. The results of each
survey are shown. Assume the population standard deviations are o₁ = $6439 and 2 $6101. At a=0.01, what should you conclude?
Entry level architects Entry level architects
In Denver, CO
x₁ = 58,300
n₁ = 39
in Lincoln, NE
x2 = 54,240
2 = 35
What are the null and alternative hypotheses for this test?
OA. Ho: H1-H211,000
Ha 1-2=11,000
OD. Ho: H1 H211,000
Ha: 1-2 ≥11,000
Calculate the standardized test statistic.
OB. Ho: H1 H2211,000
Ha 1-2 <11,000
OE. Ho: H1 H2 $11,000
Ha H1 H211,000
(Round to two decimal places as needed.)
Determine the P-value.
The P-value is
(Round to three decimal places as needed.)
What can you conclude about the data?
OA. Reject Ho. At the 1% level of significance, there is insufficient evidence to reject the claim that the difference in mean annual salaries is $11,000.
OB. Reject Ho. At the 1% level of significance, there is sufficient evidence to reject the claim that the difference in mean annual salaries is $11,000.
OC. Fail to reject Ho. At the 1% level of significance, there is sufficient evidence to reject the claim that the difference in mean annual salaries is $11,000.
OD. Fail to reject Ho. At the 1% level of significance, there is insufficient evidence to reject the claim that the difference in mean annual salaries is $11,000.
