A medical laboratory claims that the mean turn-around time for
performance of a battery of tests on blood samples is 1.98 business
days. The manager of a large medical practice believes that the
actual mean is larger. A random sample of 45 blood samples yielded
mean 2.05 and sample standard deviation 0.13 day. Perform the
relevant test at the 10% level of significance, using these
data.
State the null and alternative hypotheses: Ho: H1: This is a
_________ test and the claim is the_________ (null or alternative
hypothesis).For this study, we should use a_________ (right, left,
or two-tailed) .The p-value is:_________(round to four decimal
places). Because P_________0.10 we_________the null hypothesis.
Thus,_________.

A laboratory claims that the mean sodium level, μ , of a healthy
adult is 141 mEq per liter of blood. To test this claim, a random
sample of 26 adult patients is evaluated. The mean sodium level for
the sample is 144 mEq per liter of blood. It is known that the
population standard deviation of adult sodium levels is 11 mEq.
Assume that the population is normally distributed. Can we

Researchers wish to test the efficacy of a program intended to
reduce the length of labor in childbirth. The accepted mean labor
time in the birth of a first child is 15.3 hours. The mean length
of the labors of 13 first-time mothers in a pilot program was 10.8
hours with a standard deviation of 3.1 hours. Assuming a normal
distribution of times of labor, test at the 10% level of
significance whether the mean labor time for all women...

Let x be a random variable that represents the pH of
arterial plasma (i.e., acidity of the blood). For healthy adults,
the mean of the x distribution is typically 7.4
(Reference: Merck Manual, a commonly used reference in
medical schools and nursing programs). A new drug for arthritis has
been developed. However, it is thought that this drug may change
blood pH. A random sample of 33 patients with arthritis took the
drug for 3 months. Blood tests showed that...

Total blood volume (in ml) per body weight (in kg) is important
in medical research. For healthy adults, the red blood cell volume
mean is about μ = 28 ml/kg.† Red blood cell volume that is
too low or too high can indicate a medical problem. Suppose that
Roger has had seven blood tests, and the red blood cell volumes
were as follows.

A random
sample is selected from a normal population with a mean of µ = 30
and a standard deviation of σ= 8. After a treatment is administered
to the individuals in the sample, the sample mean is found to be x̅
=33.
Furthermore,
if the sample consists of n = 64 scores, is the sample
mean sufficient to conclude that the treatment has a significant
effect? Use a two-tailed test with α = .05.

A new kind of typhoid shot is being developed by a medical
research team. The old typhoid shot was known to protect the
population for a mean time of 36 months, with a standard deviation
of 3 months. To test the time variability of the new shot, a random
sample of 25 people were given the new shot. Regular blood tests
showed that the sample standard deviation of protection times was
1.5 months. Using a 0.05 level of significance, test...
