Suppose a normally distributed set of stock prices with 7400 observations has a mean of 148 and a standard deviation of 20. Use the 68-95-99.7 Rule to determine the number of observations in the data set expectec to be between the values 88 and 168. Hint: This problem is asking for how many observations, not the percent. (Round to the nearest whole observation.) Tip: Don't round any probabilities or percentages in your calculations. Keep all decimal places and round at the END of the problem. Answer =
