An employment information service claims the mean annual salary for senior level product engineers is $97,000. 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=0.01, test the claim that the mean salary is $97,000. Complete parts (a) through (e) below. Assume the population is normally distributed. The claim is the null hypothesis.

please don't reject this question. I just need the standardized test statistic T=_____
**Educational Website Transcription:** **Title: Testing a Claim About Mean Annual Salaries** An employment information service claims the mean annual salary for senior level product engineers is $97,000. The annual salaries (in dollars) for a random sample of 16 senior level product engineers are shown in the table to the right. At \(\alpha = 0.01\), test the claim that the mean salary is $97,000. Complete parts (a) through (e) below. Assume the population is normally distributed. **Annual Salaries:** - 100,651 - 96,333 - 93,546 - 112,633 - 82,543 - 74,213 - 77,030 - 81,017 - 102,450 - 76,175 - 103,934 - 104,036 - 91,009 - 82,069 - 85,061 - 110,404 **(a)** 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 \( t_0 = -2.95, 2.95 \). (Use a comma to separate answers as needed. Round to two decimal places as needed.) Choose the graph which shows the rejection region: - **Graph A:** Shows a shaded region to the left of \( t = -t_0 \). - **Graph B:** Shows a shaded region to the left of \( t = t_0 \). - **Graph C:** Shows a shaded central region between \( -t_0 < t < t_0 \). - **Graph D:** (Correct) Shows shaded regions outside \( -t_0 \) and \( t_0 \). **(c)** Find the standardized test statistic, \( t \). The standardized test statistic is \( t = \underline{\qquad} \). (Round to two decimal places as needed.)
