1)The average price of a college math textbook is $177 and the standard deviation is $20. Suppose that 44 textbooks are randomly chosen. Round all answers to 4 decimal places where possible. Find the third quartile for the average textbook price for this sample size. $ (round to the nearest cent) 2)The amount of syrup that people put on their pancakes is normally distributed with mean 59 mL and standard deviation 12 mL. Suppose that 15 randomly selected people are observed pouring syrup on their pancakes. Round all answers to 4 decimal places where possible. For the group of 15 pancake eaters, find the probability that the average amount of syrup is between 63.4 mL and 67.3 mL.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
