Question

**hrowback question:** In pharmacologic research a
variety of clinical chemistry measurements are routinely monitored
closely for evidence of side effects of the medication under study.
Suppose typical blood-glucose levels are *normally*
distributed with mean 98.81 mg/dl and standard deviation 21.42
mg/dl. (Note: Round all of your answers to four decimal places
where appropriate.)

- We would expect the blood glucose levels to fall between and in 99.7% of patients.
- A normal glucose range is 65 - 120 mg/dl. What is the
probability a patient's blood glucose level falls between these two
values?
- z1 =
- z2 =
- probability =

- What is the probability that a patient's blood glucose level is
greater than 40 mg/dl?
- z =
- probability =

- If a blood glucose level is in the top 2%, then the patient is
classified as abnormal. What blood glucose level corresponds to
this cut-off?
- z =
- glucose = mg/dl

Answer #1

In pharmacologic research a variety of measurements are
routinely monitored closely
for evidence of side eects of the medication under study.
Suppose typical blood-
glucose levels are normally distributed with mean 90 mg/dL and
standard deviation
38 mg/dL.
(a) Only values which in the higher 20% values are considered
abnormal. How
high should the blood-glucose level be to be classied as
abnormal?
(b) Another criteria to classify blood-glucose level as abnormal
is if the measure-
ment is greater than 138...

Question 6
An investigator is looking at the relationship between
periodontal disease and the onset of hypertension. Suppose the
investigator decides to look at height as a variable that may
confound the relationship between exposure and case status in his
study. After collecting information about the height of each
participant, he assembles a database that approximates height with
the normal distribution.
A) Assuming the mean of the distribution is 176.2 cm with a
standard deviation of 17.5 cm, what are...
