An employment information service claims the mean annual salary for senior level product engineers is $95,000. The annual salaries (in dollars) for a random sample of 16 senior level product engineers are shown in the table to the right. At a = 0.10, test the claim that the mean salary is $95,000. Complete parts (a) through (e) below. Assume the population is normally distributed.

An employment information service claims the mean annual salary for senior level product engineers is $95,000. The annual salaries (in dollars) for a random sample of 16 senior level product engineers are shown in the table to the right. At a=0.10, test the claim that the mean salary is $95,000. Complete parts (a) through (e) below. Assume the population is normally distributed. (a) Identify the claim and state Ho and Ha Ho: ▼ ▼ Ha: ▼ ▼ (Type integers or decimals. Do not round.) The claim is the hypothesis. (b) Use technology to find the critical value(s) and identify the rejection region(s). The critical value(s) is/are to = (Use a comma to separate answers as needed.
