1) A job placement director claims that the average starting salary for nurses in her city is $24,000. A random sample of ten nurses' salaries in that city has a mean of $23,400 and a standard deviation of $400. Assuming that the population is normally distributed, use the graphing calculator to find: (a) the P-value. (Round answer to five decimal places.) (b) the test statistic. (Round answer to two decimal places.) 2) A researcher reports that the average salary of assistant professors in a certain state is $42,000. A random sample of 30 assistant professors in that state has a mean salary of $43.260 and a standard deviation of $5230. Assuming that the population is normally distributed, use the graphing calculator to find the P-value. (Round answer to two decimal places.)
