b. The null and alternative hypotheses would be:
Ho: ? Select an answerv
H1: ?v Select an answerv
c. The test statistic ?v =
(please show your answer to 3 decimal places.)
d. The p-value =
|(Please show your answer to 4 decimal places.)
e. The p-value is ?a
f. Based on this, we should Select an answerv the null hypothesis.
