Question
A sample mean is 6.7, sample size is 20, and
population standard deviation is 0.6 are
given. Ho: p27.1, H₁: p<7.1 and a significance
level is 0.05. Use the P-value approach to test the
hypothesis.
O a.
a. z = -2.98; P-value = 0.9986; do not reject
null hypothesis
O b. z= -2.98; P-value = 0.0014; do not
reject null hypothesis
O c. z = -2.98; P-value = 0.0014; reject null
hypothesis
O d. z = -0.67; P-value = 0.2514; do not
reject null hypothesis
