Confidence Intervals for Population Means When the Population Standard Deviation is Unknown.

Use the table of critical values of t to find the following: Construct a confidence interval for the population mean at the given confidence level. Remember to find your degrees of freedom.

4. n = 25, x = 56, s = 8, level of confidence is 95% 2

5. n = 36, x = 23.6 s = 4.2 level of confidence is 90%

6. Level of confidence is 98%. 272, 334, 288, 299, 312, 315, 309, 275, 325, 312

When constructing confidence intervals for population means, an analyst must never use personal judgement to estimate
When constructing confidence intervals for population means, an analyst must never use personal judgement to estimate a preliminary value of the population standard deviation when attempting to select a sample size for desired margin of error.
