STAT 245 Study Guide - Confidence Interval, Standard Deviation, Peripheral Neuropathy
Document Summary
Stats 245. 3 review 1 (2013: the blood levels (mg/dl) of 50 subjects selected at random are displayed in the following table. Calculate the mean, median, and quartiles, and construct a box-and-whisker plot. Construct a 99% confidence interval for the population mean: suppose you want to construct a 95% confidence interval for mean aggression scores as above, and you can assume that the standard deviation of the estimate is 5. 95% confidence interval would have this error bound, b of 0. 4: the mean weight of 100 men in a particular heart study is 61 kg with a standard deviation of 7. 9 kg. Construct a 95% confidence interval for the mean. Page 1: the standard hemoglobin reading for normal males of adult age is 15 g/100 ml. The standard deviation is about 2. 5 g/100 ml. For a group of 36 male con- construction workers, the sample mean was 16 g/100 ml: construct a 95% confidence interval for the male construction workers.
