Test the claim that the mean salary in a town is at most $54000. A random sample 33 salaries yields an
average of $54536.16. Use a = 0.01, and assume that o = $1400.
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
e
The hypotheses are:
О Но:р — 54000; На:р + 54000
O Ho:p< 54000; Ha:p > 54000
O Ho:p > 54000; Ha:p < 54000
O Ho:µ = 54000; Ha:µ # 54000
O Ho:µ < 54000; Ha:µ > 54000
or
O Ho:µ > 54000; Ha: µ < 54000
2. This is a O rightO twoO left tailed test and the distribution used is
OT since o not known
Oz since o known
OZ since testing a proportion
The Degrees of Freedom are
O 32
O 3
ON/A since this is a Z-test
3. The STS (round to 3 decimals) is:](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F31f0fa11-21b0-49ac-899b-d195dba33dea%2Fc6dbcd78-1086-4627-a9dd-7948dadd41b5%2Fk9jc2gs_processed.jpeg&w=3840&q=75)
