Imagine that income is normally distributed (a little hard to do, but let's just it is for this problem) for members of our major political parties. Let's say the mean for Republicans is 90 (all units in thousands) with a standard deviation of 12, and the mean for Democrats is 70 with a standard deviation of 10. What is the probability that a Democrat drawn at random will score above the income associated with the 10th Percentile Rank for Republicans? (The answer must be written as a number carried to four decimal places. Only write the final answer; do not write the formula or computations used to derive the answer. Do not convert the answer to a percentage.)
