Following is a sample of 5 mathched pairs.

Sample 1  19 15  16  23  24

Sample 2  18  19  10  14  17

let u1 and u2 represent the population means and let ud=u1-u2. A test will be made of the hypothesis Ho: ud=0 versus H1:Ud greater 0.

a. Compute the differences.

b. Compute the test statistic

c. Can you reject H0 at the a= 0.05 level of significance?

Step 1

(a)

The differences is,

Step 2

(b)

Step-by-step procedure to obtain the p-value and test statistic using MINITAB software:

• Choose Stat > Basic Statistics > Paired t.
• Choose Samples in different columns.
• In sample 1, enter the column of Sample 1.
• In sample 2, enter the column of Sample 2.
• Choose Options.
• In Confidence level, enter 95.
• In Hypothesized difference, enter 0.
• In Alternative, select greater than.
• Click OK in all the dialogue boxes.

The output obtained using MINITAB software is given below:

Step 3

Thus, the test statistic is 1.61.

(c)

Rejectio...
