only
(c) both Re and
e/D

A fitness company is building a 20-story high-rise. Architects
building the high-rise know that women working for the company have
weights that are normally distributed with a mean of 143 lb and a
standard deviation of 29 lb, and men working for the company have
weights that are normally distributed with a mean of 181 lb and a
standard deviation or 32 lb. You need to design an elevator that

A manufacturer of sprinkler systems used for fire protection in
office buildings claims that the true average system-activation
temperature is 130oF. A sample of n = 9 systems, when tested,
yields a sample average activation temperature of 131.08oF. Suppose
the distribution of activation temperature is normal with standard
deviation 3.0 oF. Denote the true average system-activation
temperature by µ ( oF). Consider testing H0 : µ = 130 versus Ha : µ
6= 130 at the significance level α =...

1.
A) A manufacturer of sprinkler systems designed for fire
protection claims that the average activating temperature is at
least 135 degrees F. To test this claim, you randomly select a
sample of 32 systems and find the mean activation temperature to be
133 degrees F. Assume the population standard deviation is 3.3
degrees F. At a=0.10, do you have enough evidence to reject the
null hypothesis? 10

u<135.

A manufacturer of sprinkler systems used for fire protection in
office buildings claims that the true average system activation
temperature is 130 ◦F. A sample of n = 49 systems, when tested,
yields a sample average activation temperature of 131.08 ◦F. If the
distribution of activation times is Normal with standard deviation
of 1.5◦F, does the data contradict the manufacturer’s claim at
significance level α = 0.01?

Calculate the necessary pump horsepower across a system, along
with the pressure developed in the pump for a system containing a
liquid solution with a density of 1220 kg/m3 , moving at a
volumetric flow rate of 0.56 m3 /min. The liquid initially sits in
a large open storage tank and is transferred to the pump via a
schedule 80 stainless steel pipe with a nominal diameter of 4 in.
The discharge pipe (also schedule 80 stainless steel) from the...
