Question

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 α=0.05, test the claim that the mean salary is $95,000. Complete parts (a) through (e) below. Assume the population is normally distributed.
Annual Salaries
100	,656	96	,362	93	,494	112	,811
82	,437	74	,165	77	,080	80	,919
102	,491	76	,119	103	,984	104	,083
91	,091	82	,052	85	,116	110	,340

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
