SUMMARY OUTPUT
Referring to Table 16-8, the fitted value for 1994 is ________.
TABLE 19-5
The following payoff table shows profits associated with a set of 2 alternatives under 3

TABLE 9-12
A drug company is considering marketing a new local anesthetic. The effective time of
the anesthetic the drug company is currently producing has a normal distribution with a
mean of 7.4 minutes with a standard deviation of 1.2 minutes. The chemistry of the new
anesthetic is such that the effective time should be normally distributed with the same
standard deviation. The company will market the new local anesthetic as being better if
there is evidence that the population mean effective time is greater than the 7.4 minutes
of the current local anesthetic.
Referring to Table 9-12, if you select a sample of 25 new local anesthetics and are
willing to have a level of significance of 0.01, the probability of the company marketing
the new local anesthetic when its population mean effective time is greater than the 7.4
minutes is ________ if the population mean effective time is 8 minutes.
A personal computer user survey was conducted. The number of computer magazine
subscriptions is an example of a ________ numerical variable.
