A large Factory space has an average occupancy of 45 people (only male workers in this space) they are doing light bench work. The average light level is 1.5W/ft2 of recessed, vented to return air fluorescent fixtures. Other production equipment create a total heat gain of 3 W/ft2. Compute the total sensible and total latent heat gain for the space. The floor area is 7500 ft2. For the sensible heat gain, estimate the radiative and convective portions for each type of heat gain (in the unit of Btu/hr).

A local factory making greeting cards employs only workers and machines. Let x1 represent workers and x2 represent machines. The firm’s production function is: f(x1, x2)=10*min(x1, 1/2x2) a) Draw an isoquant representing a quantity of 100 units and an isoquant representing a quantity of 200 units. Label two points on each isoquant. b) Suppose the firm wants to produce 300 cards. The price of an hour of labor is $20 and the price of a machine hour is $30 per...

At a large factory 1% of the workers are using drugs, an event we’ll call D. An employee has just been tested by a procedure that has a 3% false positive rate and has failed the test, F. Assume that the test is always positive for people who are using drugs. (i) Find P(D|F). (ii) Suppose that the employee failed the first test (F1). What is the probability he will fail the second test (F2), i.e., compute P(F2|F1). (iii) What...

4. A lift has an occupancy warning of no more than 25 people and of total weight no more than 1950kg. For a population of users, suppose weights are normally distributed with mean 75kg and standard deviation 10kg. (a) What is the probability that the total weight of a random sample of 25 people from the population exceeds 1950kg? (b) Calculate the probability that a random sample of 24 people sets the alarm off. (c) Suppose people carry things with...

In a large company a sample of 7 people has been selected. The average amount of hours of physical activity per person per week, calculated from this sample is 2.5 hours. The standard deviation calculated from the same sample is s=0.5 hours. Assuming normality, determine the 98% Confidence Interval for the average amount of hours of physical activity per person per week in the entire company.

An article was written that on average only 35% of people read, and that the number of books that are read are correlated to the reader’s age. A simple random survey was conducted on 34 people. The binomial question being “Do you read books?”. The 2 quantitative question being: “How many books have you read in the last 2 years?” and “What is your age”. The results are below: 18 people stated they do not read, 0 books per year....
