Question

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.

Table of Annual Salaries of 12 full-time female workers over 25 without high school diploma

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.)
