It is worth noting that a triangular probability distribution with minimum value A, most likely value B, and maximum value C, has a mean value equal to (A + B + C)/3. What is the best estimate of when the SSD product will be completed? The SSD device has been promised to an important customer in 21 months. What is the likelihood that this deadline will be met? Eight technicians from Team B have been cross trained to allow them to work for Team C. Each technician transferred from Team B to Team C will increase the three parameters of B’s triangular […]

A construction company in Naples, Florida, is struggling to sell condominiums. In order to attract buyers, the company has made numerous price reductions and better financing offers. Although condominiums were once listed for $300,000, the company believes that it will be able to get an average sale price of $210,000. Let the price of these condominiums in the next quarter be normally distributed with a standard deviation of $15,000. Use Table 1. a.What is the probability that the condominium will sell at a price (i) below $200,000?, (ii) above $240,000? (Round “z” value to 2 decimal places and final answer to 4 […]

A national standard requires that public bridges over 20 feet in length must be inspected and rated every 2 years. The rating scale ranges from 0 (poorest rating) to 9 (highest rating). A group of engineers used a probabalistic model to forecast the inspection ratings of all major bridges in a city. For the year 2020, the engineers forecast that 10% of all major bridges in that city will have ratings of 4 or below. Complete parts a and b, showing work. A. Use the forecast to find the probability that in a random sample of 11 major bridges in […]
The owner of a farmer’s market was interested in determining how many oranges a person buys when they buy oranges.
The owner of a farmer’s market was interested in determining how many oranges a person buys when they buy oranges. He asked the cashiers over a weekend to count how many oranges a person bought when they bought oranges and record this number for analysis at a later time. The data is given below in the table. The random variable x represents the number of oranges purchased and P(x) represents the probability that a customer will buy x oranges. Determine the variance of the number of oranges purchased by a customer. x 1 2 3 4 5 6 7 8 […]
