I was just wondering how people feel about math as a whole? I am having a lot of issues with my College Stats course and would love to hear how others think. Whether or not a good amount of people enjoy it or not as well ranging from elementary math-college levels and beyond that
That being said, I would also appreciate if anyone could help me a little bit with one or two things.
Problems:
1. The scores of an exam are normally distributed with a mean and standard deviation of 810 and 110 respectively. Find the score you would need to achieve to place in the top 10%
2. For a medical study, a researcher wishes to select people in the middle 44% of the population based on blood pressure. Assume the mean systolic blood pressure is 110 and the standard deviation is 8. Assume also that this variable is normally distributed. Find the upper and lower limits that would qualify people for the study
