Suppose a normally distributed set of stock prices with 9000 observations has a mean of 187 and a standard deviation of 14. Use the 68-95-99.7 Rule to determine the number of observations in the data set expected to be between the values 173 and 229. Hint: This problem is asking for how many observations, not the percent. (Round to the nearest whole observation.) Answer=
