Suppose that the process time of a process is 11 minutes/unit. It
is observed that the output rate is 2 units/hour. What is the input
rate in units/minute? Round your answer to 2 decimal places (if it
has more digits than 2 digits after the decimal point).

Suppose the average time to complete a marathon is believed to
be 264 minutes. If a random sample of 67 marathon runners posted an
average time of 248 minutes, with a standard deviation of 46.6
minutes, is there evidence to support the claim that the average
time is lower than originally thought? Perform a hypothesis test
with significance level 0.01.

Suppose that an airline quotes a flight time of 135 minutes
between two cities. Furthermore, suppose that historical flight
records indicate that the actual flight time between the two
cities, x, is uniformly distributed between 115 and 155
minutes. Letting the time unit be one minute,
(a) Write the formula for the probability curve
of x.
(c) Find P(139 < x <
141). (Round your answer to 4 decimal places.)
(d) Find the probability that a randomly
selected flight between...

An IE performed a time study on a hydraulic valve installation
& test process. Each observed installation was performed by a
different production worker, so the activity factor (performance
rating) varied in each observation. A factor > 1.00 meant the
worker was performing better than normal in their observed time
(OT) (i.e, faster), while a factor < 1.00 meant the worker was
performing less normal in their observed time (OT) (ie, slower).
The allowance for personal delay and fatigue as...

hot-rolled steel.
(b) Find a 95% confidence interval for the mean time to process
hot-rolled steel.

A manual process takes 18 minutes of direct labor time and six
pounds of material to produce a product. Automating the process
requires 12 minutes of machine time and 5 pounds of material. The
cost per labor hour is $9, the cost per machine hour is $7, and the
cost per pound of materials is $11.
Find the nonvalue - added cost for the above situation.
