a. Alternative hypothesis is “greater than,” t = +2.5, df = 40.
b. Alternative hypothesis is “less than,” t = –2.5, df = 40.
c. Alternative hypothesis is “not equal,” t = 2.5, df = 40.
d. Alternative hypothesis is “greater than,” z = +1.75.
e. Alternative hypothesis is “less than,” z = – 1.75.
f. Alternative hypothesis is “not equal,” z = –1.75.
