a)
p-value = 2 * P(Z > z)
= 2 * P(Z > 2.03)
= 2 * 0.0212
= 0.0424
b)
p-value = 2 * P(Z > z)
= 2 * P(Z > 1.50)
= 2 * 0.0668
= 0.1336
c)
p-value = 2 * P(Z > z)
= 2 * P(Z > 1.40)
= 2 * 0.0808
= 0.1616
d)
p-value = 2 * P(Z > z)
= 2 * P(Z > 2.26)
= 2 * 0.0119
= 0.0238
Find the p-values for the following critical values: (Assume two sided hypothesis) 2.03 1.50 1.40 2.26
Using either the critical value rule or the p-value rule, if a one-sided null hypothesis for a single mean cannot be rejected at a given significance level, then the corresponding two-sided null hypothesis (i.e., the same sample size, the same standard deviation, and the same mean) will ______________ be rejected at the same significance level. always sometimes never
