A certain manufacturer is interested in evaluating two alternative manufacturing plans consisting of different machine layouts. Fifty eight consecutive working days were selected and each plan was monitored and the number of items produced each day was recorded. Some of the collected data is shown below:
DAY PLAN 1 OUTPUT PLAN 2 OUTPUT
1 1234 units 1311 units
2 1355 units 1366 units
3 1300 units 1289 units
. . .
. . .
Which of the following confidence intervals would indicate that Plan 2 produces a higher average output than Plan 1? Assume we are comparing (Plan 1 – Plan 2)
(-25.6, -2.6)
(-3.5, 85.6)
(45.3, 55.6)
(-10.5, 36.5)

.Tire manufacturer is interested in testing the fuel economy for
two different tread patterns. Tires of each tread type were driven
for 1000 miles on each of 9 different cars. The mileages, in miles
per gallon, were as follows. Test whether the mean mileage is the
same for both types of tread. (ANOVA test)

A manufacturer of electronic components is interested in
determining the lifetime of a certain type of battery. A sample, in
hours of life, is as follows 123, 116, 122, 110, 175, 126, 125,
111, 118, 117.
Calculate: Sample Mean, Sample Median, 20% trimmed Mean,
Quartiles: Q1, Q2 and Q3
Interquartile range: IQR = Q3 –Q1 , Lower bound = Q1 - 1.5(Q3

Q1.A manufacturer is considering a purchase of a new
manufacturing machine, called Machine A. Machine A is expected to
save $9,000 per year and it costs $21,000 to purchase. The expected
useful life of the machine is 3 years and there is no expected
residual value at the end of the 3 years. The minimum acceptable
rate of return is 8%.
A)What is the net present value of Machine A? (round to nearest

A researcher is interested in evaluating a certain brand of
radial auto tire. Twenty tires are randomly selected from retail
outlets throughout the country, and each is placed on a special
machine which rotates the tires at a constant speed (equivalent to
55 miles per hour) against the friction equivalent of a 4000 pound
auto being driven on a smooth highway. Each tire is run until there
is no tread left. The number of miles (in thousands) were as
follows:...

A certain firm is evaluating the proposed acquisition of a new
milling machine. The cost
of machine is Rs. 1,000,000 and it would cost another Rs. 200,000
to modify it for
special use. The firm has been using the straight-line depreciation
assuming 5 years life
and Rs 100,000 of salvage value. The machine would require an
increase in net working
capital (inventory) of Rs.100,000. The milling machine would have
no effect on
revenues, but it is expected to save the...
