Answer
a) fail to reject the null hypothesis
b)there is not sufficient evidence to support that the mean height of women is not 160 cm.
Work Step by Step
a) If the P-value is less than $\alpha$, which is the significance level, then this means the rejection of the null hypothesis. Hence:P=0.0614 is more than $\alpha=0.05$, hence we fail to reject the null hypothesis.
b) Hence this means that there is not sufficient evidence to support that the mean height of women is not 160 cm.
