Question
A sample mean is 137, sample size is 20, and
population standard deviation is 14.2 are
given. Ho: μ-132, H1: µ#132 and a significance
level is 0.05. Use the P-value approach to test the
hypothesis.
O a.
a.
z = 2.57; P-value = 0.0101; reject null
hypothesis
b. z = 0.35; P-value = 0.7263; do not reject
null hypothesis
O c. z = 1.57; P-value = 0.0582; do not
reject null hypothesis
O d. z = 1.57; P-value = 0.1164; do not reject
null hypothesis
