A psychologist found that a common perception among both men and women is that women tend to be more empathetic than men. She set out to determine if there were data to support this claim. She administered a diagnostic that measures the level of empathy on a scale from 0–28. Below are the scores for a random sample of 16 men and and a random sample of 16 women.

A survey was conducted among 92 men and 217 women and got their BMI values. Among the 92 men, the average BMI is 24.4 with standard deviation 3.4. Among the 217 women, the average BMI is 22.3 and standard deviation is 3.6. (1) Assuming that BMI follows a normal distribution, please calculate what values of BMI that the 95% of men and women will have. In other words, 95% of men and women’s BMI will be within what range. Please...
