Question: Calculate the test statistic and p-value for each sample. a) 0: = 0.20 versus 1: 0.20, = 0.025, = 0.28, = 100 b) 0: 0.50
Calculate the test statistic and p-value for each sample.
a) 0: = 0.20 versus 1: 0.20, = 0.025, = 0.28, = 100
b) 0: 0.50 versus 1: > 0.50, = 0.025, = 0.60, = 90
c) 0: 0.75 versus 1: > 0.75, = 0.10, = 0.82, = 50
