You may need to use the appropriate technology to answer this question.
Consider the following hypothesis test.
H0: 50
Ha: < 50
A sample of 36 is used. Identify the p-value and state your conclusion for each of the following sample results. Use
= 0.01.
(a) x = 49 and s = 5.3
Find the value of the test statistic. (Round your answer to three decimal places.)....?
Find the p-value. (Round your answer to four decimal places.)
p-value = ....?
State your conclusion.
Reject H0. There is insufficient evidence to conclude that < 50.
Do not reject H0. There is insufficient evidence to conclude that < 50.
Reject H0. There is sufficient evidence to conclude that < 50.
Do not reject H0. There is sufficient evidence to conclude that < 50.
(b) x = 48 and s = 4.6
Find the value of the test statistic. (Round your answer to three decimal places.)...?
Find the p-value. (Round your answer to four decimal places.)
p-value =...?
State your conclusion.
Reject H0. There is insufficient evidence to conclude that < 50.
Do not reject H0. There is insufficient evidence to conclude that < 50.
Reject H0. There is sufficient evidence to conclude that < 50.
Do not reject H0. There is sufficient evidence to conclude that < 50.
(c) x = 51 and s = 5.0
Find the value of the test statistic.....?
Find the p-value. (Round your answer to four decimal places.)
p-value = ...?
State your conclusion.
Reject H0. There is insufficient evidence to conclude that < 50.
Do not reject H0. There is insufficient evidence to conclude that < 50.
Reject H0. There is sufficient evidence to conclude that < 50.
Do not reject H0. There is sufficient evidence to conclude that < 50.
