An employment information service says the mean annual pay for full-time female workers over the age of 25 and without high school diplomas is $17,000. A random sample of the annual salaries of 12 full-time female workers over 25 without high school diplomas is listed below.

Data

$15,316

$16,631

$17,328

$18,161

$16,009

$16,790

$17,503

$18,801

$16,114

$17,176

$18,028

$19,264

We are interested in testing the claim that the mean salary is $17,000. State and verify the assumptions and conditions necessary to complete this hypothesis test. (You do not have to actually complete the hypothesis test; simply determine whether the criteria are met in order for you to move forward in doing so.)
