A medical supply firm wishes to compare the mean daily output of its three plants in Toledo, Ohio; Ottumwa, Iowa; and Crab Apple Cove, Maine. Data were collected (measured in hundreds of units) for each site and are listed here.
Toledo: 10 12 15 18 9 17 15 12 18
Ottumwa: 15 17 18 12 13 11 12 11 12
Crab Apple Cove: 12 17 15 15 18 12 13 14 14
a. For each of the three plants, calculate the sum of the squared deviations around the mean of that plant.
b. Ignore the plant information (consider the data set, one sample with 27 observations). Calculate the sum of squared deviations around the mean of that group.
c. At the 10 percent level of significance, test to see if there is a difference in the means of the three plants.

A quality control engineer wishes to estimate the mean output
voltage of a DC power supply for different loads. The engineer
measures output voltage when the supply is connected to 11
different loads and computes a mean 98.4 V and standard deviation 7
V. Assume that the output voltages follow a normal
distribution.
(a) Construct and interpret the 99.9% confidence interval.
(b) Construct and interpret the 90% prediction interval.

The following table shows a part of the daily labor-output
relationship for a firm. In this table q is the quantity of output
produced and L the amount of labor required to produce the
corresponding level of output. For example, to produce 2 units of
output per day we need a total of 50 units of labor and to produce
5 units per day we need a total of 120 units of labor. The wage
rate is $40 per day...

A firm is currently producing 80 units of output. At this level
of output produced:
its average total cost is 100 (ATC = 100
) The market price per unit of output is 120
MR = 40 MC = 20
i. Is this firm making profits or losses? How much?
ii. Are they maximum profits? Why?
iii. If your answer to part ii was no, what does this firm have
to do with maximize its profits?

1. A firm operates with the production function
Q=K2L. Q represents the daily output when the firm rents
K units of capital and employs L workers. The manager has been
given a production target: Produce 8,000 units per day. She knows
the daily rental price of capital is $400 per unit. The wage rate
paid to each worker is $200 per day.
a. Currently the firm employs 80 workers per day. What is the
firm’s total daily cost of producing...
