4.13 A sample consisting of four pieces of luggage was selected from among those checked at an airline counter, yielding the following data on x 5 weight (in pounds):

x1 = 33.5, x2 = 27.3, x3 = 36.7, x4 = 30.5

treatment with large doses of penicillin. Three days later, temperatures were recorded, and the treatment was con- sidered successful if there had been a reduction in a pa- tient’s temperature. Denoting success by S and failure by F, the 10 observations are

S      S      F      S      S      S      F      F      S      S

a.      What is the value of the sample proportion of successes?

b.       Replace each S with a 1 and each F with a 0. Then calculate x for this numerically coded sample. How does x compare to p^ ?

c.       Suppose that it is decided to include 15 more pa- tients in the study. How many of these would have to be S’s to give p^ = .80 for the entire sample of 25 patients?
