Answer the following question
The level of lead in the blood was determd for a sample of 152 male hazardous waste workers age 20-30 and also for a sample of 85 female workers, resulting in a mean t standard error of 5.3 +0.3 for the men and 3.80.2 for the women. Calculate an estimate of the Merence between true average blood lead levels formale and female workers in a way that provides information about reliability and precision (Use a 95%...

MALE FEMALE Count 28 21 Mean 72.8 72.4 Standard Deviation 5.3 7.7 A researcher wanted to see whether there was a significant difference in resting pulse rates for men and women. The data she collected is summarized to the right. For both groups, the data appear to be unimodal and symmetric. Is this evidence that resting pulse rates for men are higher than for women? Test an appropriate hypothesis using a significance level of 0.10 (? = 0.10). You can...

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,...
