Question

There (is/is not) enough evidence at the ___% level of significance to (support/ Reject) the claim that the mean annual salary for senior level product engineers is 

An employment information service claims the mean annual salary for senior level product engineers is $98,000. 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 $98,000. Complete parts (a) through (e) below. Assume the population is normally distributed. Annual Salaries 100,725 82,577 102,534 91,056 112,738 O 80,913 103,953 110,362 96,338 93,507 77,058 74,224 76,207 103,956 82,047 85,148 (a) Identify the claim and state Ho and Ha. Ho: 98000 Hạ: 98000 (Type integers or decimals. Do not round.) The claim is the null hypothesis. (b) Use technology to find the critical value(s) and identify the rejection region(s). The critical value(s) is/are to - 1.75,1.75. (Use a comma to separate answers as needed. Round to two decimal places as needed.) Choose the graph which shows the rejection region.
