Question:
For each of the tests in question 4a-c, state E(S) and Var(S) and hence the value of the test statistic, when approximating to the normal distribution.
Question 4a-c
a. H0: The population median is 38.
H1: The population median is less than 38.
S+ = 4, n = 15.
b. H0: The population median is 16.2.
H1: The population median is not 16.2.
S+ = 5, n = 20
c. H0: The population median is 154.
H1: The population median is greater than 154.
S+ = 11, n = 15
