Medical research has shown that repeated wrist extension beyond 20 degrees increases the risk of wrist and hand injuries. Each of 24 students at a university used a proposed new computer mouse design. While using the mouse, each student's wrist extension was recorded. Data consistent with summary values given in a paper are given. Use these data to test the hypothesis that the mean wrist extension for people using this new mouse design is greater than 20 degrees. (Use α = 0.05. Use a statistical computer package to calculate the P-value. Round your test statistic to two decimal places and your P-value to three decimal places.)

Two proposed computer mouse designs were compared by recording
wrist extension in degrees for 24 people who each used both mouse
designs.† The difference in wrist extension was calculated by
subtracting extension for mouse type B from the wrist extension for
mouse type A for each person. The mean difference was reported to
be 8.82 degrees. Assume that this sample of 24 people is
representative of the population of computer users.
(a)
Suppose that the standard deviation of the differences...

A medical study has shown that the first 20 days of radiation
therapy, a particular type of malignant tumor decreases at a rate
according to the function M'(t)=−0.015t^2+0.01t where MM represents
the mass (in grams) of the tumor and tt is the time (in days) since
the beginning of the radiation treatment. If a tumor of this
particular type has a mass of 150 grams just prior to the start of
radiation treatment,
a. Rounded to the nearest tenth, at...

effects of “secondhand” smoke. If you are a smoker and you wish to
continue smoking, describe the effect of the following legislative
proposals on your behavior. As a result of these programs, do you
benefit? Does society as a whole benefit? Please restrict your

Many medical professionals believe that eating too much red meat
increases the risk of heart disease and cancer. Suppose you would
like to conduct a survey to determine the annual consumption of
beef by a typical American and want to use four pounds as the
desired margin of error for a confidence interval of the population
mean. Assume the population standard deviation is 20 pounds.
Determine the sample size when:
a)A 90% confidence interval is desired for the mean amount...

A
substance has a melting point of 20 degrees celsius and a heat of
fusion of 3.4*10^ 4 J/kg. The boiling point is 150 degrees celsius
and heat vaporization is 6.8*10^ 4 J/kg at a pressure of one
atmosphere. The specific heats for the solid,liquid and gaseous
phases are 600 J/kg , 1000 and 400. How much heat is required to
raise the temperature 1.90kg of this substance from -4 degrees
celsius to 106 degrees celsius at a pressure of...

Ask Your Teacher Recent studies have shown that about 20% of
American adults fit the medical definition of being obese. A large
medical clinic would like to estimate what percentage of their
patients are obese, so they take a random sample of 100 patients
and find that 16 are obese. Suppose that in truth, the same
percentage holds for the patients of the medical clinic as for the
general population, 20%. If the clinic took repeated random samples
of 100...

It has been suggested that occupational exposure to benzene in
the petroleum industry increases the risk of developing leukemia.
The levels of benzene to which workers in this industry have been
exposed were high from 1940 to 1970, but since 1970 have been
significantly reduced. What kind of study design, using petroleum
workers, would provide the most useful information on whether
benzene affects incidence rates of leukemia in this industry? (You
may assume that records of individual worker assignments to...
