Suppose the High-density lipoprotein (HDL) cholesterol levels of
20 subjects were measured before and after the treatment. We want
to find out if, in general, the treatment will lead to improvements
of health, i.e., increasing the HDL cholesterol level. The mean and
standard deviation of the difference are 2.05, 2.837, respectively.
We assume the differences follow normal. Use ? =0.05.

For a healthy human, a body temperature follows a normal
distribution with Mean of 98.2 degrees Fahrenheit and Standard
Deviation of 0.26 degrees Fahrenheit. For an individual suffering
with common cold, the average body temperature is 100.6 degrees
Fahrenheit with Standard deviation of 0.54 degrees Fahrenheit.
Simulate 10000 healthy and 10000 unhealthy individuals and answer
questions 14 to 16.

which of the events are the most likely? Pick...

The level of calcium
in the blood of healthy young women follows a normal distribution
with mean μ = 10.5 milligrams per deciliter and standard deviation
σ = 0.25 . To find out if the calcium level changes during
pregnancy, a group of 30 healthy pregnant young women is randomly
selected and their the calcium level at their first visit for
prenatal care is measured.
Specifically, the
following hypotheses are tested:
H0: μ p =
10.5 , Ha: μ p...

The level of magnesium in the blood of healthy young adults
follows a normal distribution, with mean μ = 10 milligrams per
deciliter and standard deviation σ = 0.4. A clinic measures the
magnesium of 25 healthy pregnant young women at their first visit
for prenatal care. The sample mean of these 25 measurements is 9.6.
Is this evidence that the mean magnesium level in the population
from which these women come is less than 10? To answer this, test...

student will be between 68 and 77 inches tall? A. 3.60 B. 0.2119
C. 0.6580 D. 0.7855
The amount of water consumed each day by a healthy adult follows a normal distribution with...
The amount of water consumed each day by a healthy adult follows
a normal distribution with a mean of 1.46 liters.A health campaign
promotes the consumption of at least 2.0 liters per day: A sample
of 10 adults after the campaign shows the following consumption in
liters:
1.78 1.90 1.38
1.60 1.80 1.30
1.56 1.90
1.90 1.68
At the 0.050 significance level, can we conclude that water
consumption has increased? Calculate and interpret the p-value.

liters: 1.35 1.42 1.34 1.42 1.44 1.64 1.90 1.64 1.50 1.38 At the
0.025 significance level, can we conclude that water consumption
has increased? Calculate and interpret the p-value.

The diameter of a cylinder follows a normal distribution with
the mean of 10cm and the variance of 0.04 cm^2.
a) Construct a Shewhart chart to monitor the process mean of
cylinder diameter with a sample size 9? (Use L=3)
