8. This problem is about using the Normal Probability Calculator to get better approximations than the 68-95- 99.7% (Empirical) Rule gives us. a. According to the 68-95-99.7% (Empirical) Rule about % of a normal distribution has a z-score between 2 and -2. (Remember the z-score is the number of standard deviations from average). b. Use the Normal Probability Calculator to find the actual percentage between 2 and -2. For the mean and standard deviation use 1 and 0 respectively. (This gives what is called the standard normal distribution which is the distribution of z-scores from any normal distribution). Include a sketch.
