First introduced in Los Angeles the concept of Korean style

First introduced in Los Angeles, the concept of Korean style tacos sold from a catering truck has been gaining popularity nationally (The New York Times, July 27, 2010). This taco is an interesting mix of corn tortillas with Korean-style beef, garnished with onion, cilantro and a hash of chili-soy dressed lettuce. Suppose one such taco truck operates in the Detroit area. The owners have estimated that the daily consumption of beef is normally distributed with a mean of 24 pounds and a standard deviation of 6 pounds. While purchasing too much beef results in wastage, purchasing too little can disappoint customers.
a. Determine the amount of beef the owners should buy so that it meets demand on 80 percent of the days.
b. How much should the owners buy if they want to meet demand on 95 percent of the days?

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.
