Suppose a normally distributed set of data with 8900 observations has a mean of 123 and a standard deviation of 16. Use the 68-95-99.7 Rule to determine the number of observations in the data set expected to be above a value of 107. Round your answer to the nearest whole value. Hint: This problem is asking for how many observations not the percent. Answer Tip: Don't round any probabilities or percentages in your calculations. Keep all decimal places and round at the END of the problem.
