    3. Suppose you are asked to draw a random sample of men and women in order to measure their "emotional IQ'. The emotional IQ scale that you administer has a minimum of 0 and a maximum of 100, with higher scores indicating higher emotional intelligence. You sample 25 men and 25 women. The mean for men is 70 with a standard deviation of 10, and the mean for women is 82 with a standard deviation of 15. Using this information,...

    In a study done by the Scottish government, the average weekly earnings for men were found to be substantially higher than for women. Specifically, the average gross individual weekly income for a random sample of men was £317; for a random sample of women, it was £172 (source: Social Focus on Men and Women, scotland.gov.uk). If the samples included 1500 men and 1200 women, and the sam- ple standard deviations were £89 for the men and £67 for the women,...

    In a study on cholesterol levels a sample of 12 men and women was chosen. The plasma cholesterol levels (mmol/L) of the subjects were as follows: 6.0, 6.4, 7.0, 5.8, 6.0, 5.8, 5.9, 6.7, 6.1, 6.5, 6.3, and 5.8. We assume that these 12 subjects constitute a simple random sample of a population of similar subjects. Find a 95% confidence interval for the population standard deviation of the plasma cholesterol levels.
