with the best profit projections. PROCEDURE: FIRST: As indicated in the memo of the Management department, we need to use the sales forecaster’s prediction de approximate the demand distribution. We assume “X” to be the demand of the new toy. X follows a normal distribution with a mean “µ=20,000” and a standard deviation “σ” (unknown). As stated before, Specialty’s senior sales forecaster predicted an expected demand of 20,000 unites with a 95% probability percentage that demand would be between

corresponding relative frequency is 0.2. What does the 0.2 value indicate? 3. When you add the values 3, 5, 8, 12, and 20 and then divide by the number of values, the result is 9.6. Which term best describes this value: average, mean, median, mode, or standard deviation? 4. What is the range of the values 2.0, 3.7, 4.9, 5.0, 5.7, 6.7, 8.5, and 9.0? What is the mean? Total/Quantity of values = 45.5/8 = 5.6875, which equates to 5.69 when rounded What is the mode? 2.0, 3.7, 5.0, 5.7, 6.7, 8.5, and 9.0
