Question

3. Alpha is the probability of a type 1 error, the risk we are willing to take of rejecting H0 when it's true. The critical value(s) bound the reject region(s) with probability alpha. Pvalue is the probability of an equal or more extreme test statistic computed assuming H0 is true.

Mark the two Decision Rules for rejecting H0 that apply to this problem.

Test statistic > positive critical value of upper tail test

Test statistic < negative critical value of lower tail test

Test statistic falls outside interval (negative critical value of lower tail, positive critical value of upper tail) of two-tailed test.

pvalue <

Explanation / Answer

Alpha is the probability of a type 1 error, the risk we are willing to take of rejecting H0 when it's true. The critical value(s) bound the reject region(s) with probability alpha. Pvalue is the probability of an equal or more extreme test statistic computed assuming H0 is true.

Answer:

pvalue <

Test statistic falls outside interval (negative critical value of lower tail, positive critical value of upper tail) of two-tailed test.
