Chapter 7.2, Problem 6TY

Repeat Example 6 using a level of significance of α = 0 01.

EXAMPLE 6

Using Technology to Find a P-Value

Use the TI-84 Plus displays to make a decision to reject or fail to reject the null hypothesis at a level of significance of α = 0.05.

Chapter 7.2, Problem 6TY, Repeat Example 6 using a level of significance of  = 0 01. EXAMPLE 6 Using Technology to Find a

SOLUTION

The P-value for this test is 0.0440464253. Because the P-value is less than α = 0.05, you reject the null hypothesis.

Students have asked these similar questions
A researcher conducts a hypothesis test on a population proportion. Her null and alternative hypothesis are H0:p = 0.4 and Ha: p < 0.4. The test statistic and p-value for the test are z = -3.01 and p-value = 0.0013. For asignificance level of a= 0.05, choose the correct conclusion regarding the null hypothesis.H0:________________________ Ha:_______________________Compare the p-value and a:_______________Decision:_________________________Conclusion:___________________________________________________________
Select all that apply  Reject the null hypothesis. Fail to reject the null hypothesis.   There is insufficient evidence at the α=0.10 level of significance to conclude that the population mean flight distance of the Lightning is different than the population mean flight distance of the Thunder. There is sufficient evidence at the α=0.10 level of significance to conclude that the population mean flight distance of the Lightning is different than the population mean flight distance of the Thunder.
