Suppose that the salaries, in thousands of dollars, of themanagers for an industryare normally distributed with an unknown mean and standard deviation. Thesalaries of 26 randomly sampledmanagers are used to estimate the mean of the population. What t-score should be used to find the 95% confidence interval for the population mean?
df | t0.10 | t0.05 | t0.025 | t0.01 | t0.005 |
---|---|---|---|---|---|
... | ... | ... | ... | ... | ... |
22 | 1.321 | 1.717 | 2.074 | 2.508 | 2.819 |
23 | 1.319 | 1.714 | 2.069 | 2.500 | 2.807 |
24 | 1.318 | 1.711 | 2.064 | 2.492 | 2.797 |
25 | 1.316 | 1.708 | 2.060 | 2.485 | 2.787 |
26 | 1.315 | 1.706 | 2.056 | 2.479 | 2.779 |
Use the portion of the table above or a calculator. If you use a calculator, round your answer to three decimal places.
