Question

Consider the following competing

hypotheses:

 Hypotheses: H0μD ≤ 5; HAμD > 5 


Sample results: d = 7.3, sd = 6.2, n = 13 


 

The following results are obtained using matched samples from two normally distributed populations:


 

a-1.Calculate the value of the test statistic. (Round all intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.)


 

  Test statistic  


 

a-2.Assume normality to approximate the p-value.  

 0.010 < p-value < 0.025

0.10 < p-value < 0.2

0.05 < p-value < 0.10

0.025 < p-value < 0.05

0.005 < p-value < 0.010


 

b.Use the 5% significance level to make a conclusion.

 Reject H0 since the p-value is less than α.

Reject H0 since the p-value is more than α.

Do not reject H0 since the p-value is less than α.

Do not reject H0 since the p-value is more than α.
