Repeat the previous problem but with a non-normal population. Specifically, generate n random numbers from a fifty- fifty mixture of two normal distributions with respective means 90 and 110 and common standard deviation 10. You can do this with the formula = IF(RAND()<0.5,NORM. INV(RAND(),90,10),NORM.INV(RAND(),110,10)) This is not a normal distribution because it has two peaks.)
