What is the decision rule when using the p-value approach to hypothesis testing? Multiple Choice Do not reject H0 if the pvalue < 1-α. Reject Ho if the p-value > a Do not reject H0 if the p-value > 1-α Reject Ho if the p-value < α.

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

Identify the null hypothesis,
alternative hypothesis, test statistic, P-value, conclusion about
the null hypothesis, and final conclusion that addresses the
original claim. Use the P-value method. Use the normal
distribution as an approximation of the binomial distribution.
