variables that affect the expected salary at the restaurant. First‚ the number of meals obeys a normal distribution with a mean of 3‚000 and a standard deviation of 1‚000. Second‚ the revenue per meals is $20.00 with a probability of 25%‚ $18.50 with a probability of 35%‚ $16.50 with a probability of 30%‚ and $15.00 with a probability of 10%. Third‚ the labor cost follows a continuous uniform distribution between $5‚040 and $6‚860. He also estimates that there are two fixed costs. One is the fixed

matrices appear. The diagonal entries are the same kinds of sums of squares that appear in univariate ANOVA. The off-diagonal entries are corresponding sums of products. Under normality assumptions about error distributions‚ the counterpart of the sum of squares due to error has a Wishart distribution. Analogous to ANOVA‚ MANOVA is based on the product of model variance matrix‚ Σmodel and inverse of the error variance matrix‚ [pic]‚ or [pic]. The hypothesis that Σmodel = Σresidual implies that the product A∼I[2]

edition‚ p 219 Sample Distribution and Sampling Error Distributions of populations of scores have been discussed. However‚ a single score does not accurately represent the population. A sample‚ or subset‚ of the population is a better estimator of the population. Alternatively‚ a sample that has received some treatment can be compared to the original population. Just as there is a distribution of scores for a population‚ there is a distribution of samples (or sampling distribution) for a population

Specialty’s senior sales forecaster predicted an expected demand of 20‚000 units with a 0.95 probability that demand would be between 10‚000 units and 30‚000 units. Questions 1. Approximate the demand distribution using Normal distribution and sketch the distribution. 2. Compute the probability of a stock-out for the order quantities suggested by members of the management team. 3. Compute the projected profit for the order quantities
