a) If you have scores and you don't know the shape of their distribution, find the minimum proportion of scores that fall within 2.3 standard deviations on both sides of the mean? Round to two decimal places. b) If you have scores and you don't know the shape of thier distribution, how many standard deviations on both sides of the mean do we need to go to have 71 percent of the scores? Round to one decimal place. Hint: In part b you will need to solve for k in the chebyshev's equation.
