HW problems for the Nonparametric testing  Section 15.1, D7 p. 607  [D6 p. 676]  # 5 use  α  = 5% Wilcoxon Signed Rank P1)   The  sign test   can be used with paired data.  Suppose you expect few plus signs and many  negative signs.  Let  S   equal the number of positive signs in a sample of size n = 20.   (a) Specify every possible value of the test statistic  S  and the probability of each value under the  null hypothesis H o :   P(+)  =  P(-)  =  0.50 If H o  is true, then  S   has a binomial distribution with parameters n = 20 and p = 0.50.   (b) If one wanted to test H o  versus H a   P(+) < 0.50 with a type I error  α near 0.05, for what values of  S  would you reject H o ?   (c) What is the actual value of
