Question
You may need to use the appropriate appendix table or technology to answer this question.
Consider the following hypothesis test.
Họ: 2 20
HR< 20
A sample of 50 provided a sample mean of 19.3. The population standard deviation is 2.
(a) Find the value of the test statistic. (Round your answer to two decimal places.)
(b) Find the p-value. (Round your answer to four decimal places.)
p-value =
(C) Using a = 0.05, state your conciusion.
Reject Hg. There is sufficient evidence to conclude that u< 20.
Reject H. There is insufficient evidence to conclude that u< 20.
O Do not reject H. There is sufficient evidence to conclude that u < 20.
O Do not reject H. There is insufficient evidence to conclude that a < 20.
(d) State the critical values for the rejection rule. (Round your answer to two decimal places. If the test is one-tailed, enter NONE for the unused tail.)
test statistic s
test statistic2
State your conclusion,
O Reject H There is sufficient evidence to conclude thatu< 20.
Reject H There is insufficient evidence to conclude that a < 20.
Do not reject H There is sufficient evidence to conclude that u< 20.
Do not reject Ho. There is insufficient evidence to condlude that u < 20.
