According to the WHO MONICA Project the mean blood pressure for people in China is 128 mmHg with a standard deviation of 23 mmHg (Kuulasmaa, Hense&Tolonen, 1998). Blood pressure is normally distributed.
A.State the random variable.
B. Suppose a sample of size 15 is taken. State the shape of the distribution of the sample mean.
C. Suppose a sample of size 15 is taken. State the mean of the sample mean.
D.Suppose a sample of size 15 is taken. State the standard deviation of the sample mean.
E. Suppose a sample of size 15 is taken. Find the probability that the sample mean blood pressure is more than 135 mmHg.
F. Would it be unusual to find a sample mean of 15 people in China of more than 135 mmHg? Why or why not?
If you did find a sample mean for 15 people in China to be more than 135 mmHg, what might you conclude?

For the questions on this project assume that the mean
systolic blood pressure of adults in
America is 120 millimeters of mercury (mmHg) with a
standard deviation of 5.6 mmHg. Also
assume the variable is normally
distributed.
1) Your company develops a new treatment for high blood
pressure. You want to test it on
people who are in the 90th
percentile or higher (people who have a higher systolic
blood
pressure than 90% of other Americans). What is the
cut-off...

The mean systolic blood pressure for people in the United States
is reported to be 122 millimeters of mercury (mmHg) with a standard
deviation of 22.8 millimeters of mercury. The wellness department
of a large corporation is investigating if the mean systolic blood
pressure is different from the national mean. A random sample of
200 employees in a company were selected and found to have an
average systolic blood pressure of 124.7 mmHg.
a) What is the probability a random...

The mean diastolic blood pressure for a random sample of 100
people was 81 millimeters of mercury. If the standard deviation of
individual blood pressure readings is known to be 10 millimeters of
mercury, find a 90% confidence interval for the true mean diastolic
blood pressure of all people. Then complete the table below.
Carry your intermediate computations to at least three decimal
places. Round your answers to one decimal place.

The mean diastolic blood pressure for a random sample of 80
people was 99 millimeters of mercury. If the standard deviation of
individual blood pressure readings is known to be 11 millimeters of
mercury, find a 95% confidence interval for the true mean diastolic
blood pressure of all people. Then complete the table below.
Carry your intermediate computations to at least three decimal
places. Round your answers to one decimal place. (If necessary,

According to the National Center for Health Statistics, the mean
systolic blood pressure for males 35 to 44 years of age is 128. The
health director of a large company wonders if this national average
holds for the company's middle-aged male employees. The director
examines the medical records of a random sample of 72 male
employees in this age group and records each of their systolic
blood pressure readings.
State an appropriate pair of hypotheses for a
significance test in...
