How are equivalence tests different from standard hypothesis tests?
What is the difference between equivalence testing and non - inferiority?
What is a pooled standard deviation and when can it be applied?
Describe the 1 : 1 correspondence between hypothesis tests and confi dence
intervals. How do confi dence intervals give you more information than
p - values?
D e fi ne the following quantities:
(a) Hypothesis test
(b) Null hypothesis
(c) Alternative hypothesis
(d) Signifi cance level
(e) Power of the test
(f) Power function
(g) p - value
(h) Type I error
(i) Type II error
In a factory, an occupational medicine physician who was conducting a
medical research study found the mean blood level of the clerical workers
was 11.2 based on a sample. State the null and alternative hypotheses
when testing to see if the population of clerical workers has a mean blood
level of 11.2.
Describe the difference between a one - tailed and a two - tailed test and
describe situations where one is more appropriate than the other.
D e fi ne specifi city and sensitivity and relate them to the type I and type II
error rates.
What are meta - analyses? Why might they be needed?
Based on the data in Table 6.1 , do you think it is plausible that the true
mean difference in temperature between New York and Washington would
be 3 ° F? Would the power of the test be higher, lower, or the same if the
true mean difference were 5 ° F? Does the power depend on the true mean
difference? If so, why?
