Test the claim that the percentage of workers in a city that are employed full time is more than 81%. A random sample of 74 workers finds that 83.78% work full time. Use a = 0.05. 1. The sample size restriction for this test is: O Need at least 5 successes and 5 failures O Need n > 30 O None needed since population is normally distributed The hypotheses are: О Но:р 3 0.81%; На:р + 0.81 О Но:р < 0.81;B На:р > 0.81 O Ho:p 0.81; Ha:p < 0.81 O Ho:u <81; Ha:u > 81 O Ho:u = 81; Ha:u+ 81 Ο Ho: μ > 81; Ha μ < 81 2.

3. The STS (round to 3 decimals) is:
The P-value (round to 4 decimals) is:
4. The decision at a = 0.05 is:
O Reject Ho since P < a
O Reject Ho since P > a
O Do not reject Ho since P > a
O Do not reject Ho since P < a
The conclusion is:
O There is sufficient evidence to conclude that the percentage of workers who are employed full time
is more than 81%
O There is insufficient evidence to conclude that the percentage of workers who are employed full
time is not more than 81%
O There is insufficient evidence to conclude that the percentage of workers who are employed full
time is more than 81%
O There is sufficient evidence to conclude that the percentage of workers who are employed full time
is not more than 81%

Test the claim that the percentage of workers in a city that are employed full time is more than 81%. A
random sample of 74 workers finds that 83.78% work full time. Use a = 0.05.
1. The sample size restriction for this test is:
O Need at least 5 successes and 5 failures
O Need n > 30
O None needed since population is normally distributed
The hypotheses are:
O Ho:p = 0.81; Ha:p# 0.81
О Но:р < 0.81;B На:р > 0.81
O Ho:p 0.81; Ha:p < 0.81
O Ho:u < 81; Ha:u > 81
Ο Ho:μ = 81; Ha: μ 481
O Ho:u 81; Ha:u < 81
2. This is a O leftO rightO two 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
O74
ON/A since this is a Z-test
