Locate the Manufacturer tab. Test to determine if there is asignificant difference between Mean Value Added by the manufacturer and the mean Cost of Materials in manufacturingassuming a 1% level of significance. Using the results of the two-sample t-test performed on Excel, at a 1% level ofsignificance, what conclusion can you draw for this research study? Why?a. There is not a significant difference between the mean value added and the mean cost of materials in manufacturingwith a p-value of 0.51.b. There is a significant difference between the mean value added and the mean cost of materials in manufacturing witha p-value of 0.26.c. There is not a significant difference between the mean value added and the mean cost of materials in manufacturingwith a p-value of 0.26.O d. There is a significant difference between the mean value added and the mean cost of materials in manufacturing witha p-value of 0.51.

Use the file on Blackboard called "Excel Databases.xlsx". Locate the Manufacturer tab. Test to determine if there is a
significant difference between Mean Value Added by the manufacturer and the mean Cost of Materials in manufacturing
assuming a 1% level of significance. Using the results of the two-sample t-test performed on Excel, at a 1% level of
significance, what conclusion can you draw for this research study? Why?
a. There is not a significant difference between the mean value added and the mean cost of materials in manufacturing
with a p-value of 0.51.
b. There is a significant difference between the mean value added and the mean cost of materials in manufacturing with
a p-value of 0.26.
c. There is not a significant difference between the mean value added and the mean cost of materials in manufacturing
with a p-value of 0.26.
O d. There is a significant difference between the mean value added and the mean cost of materials in manufacturing with
a p-value of 0.51.

Expert Solution

Step 1

In the given situation,

The two population variances are not equal from the conclusion of F test.

Excel Procedure:

Enter the data for ‘Cost of materials’ and ‘Value added by Mfg’ in Excel sheet.
Go to Data
Click on Data Analysis.
Select ‘t-Test: Two-Sample Assuming UnEqual Variances’ and click on ‘OK’
Select the column of ‘Cost of materials’ under ‘Variable 1 Range’.
Select the column of ‘Value added by Mfg’ under ‘Variable 2 Range’.
Enter 0 under ‘Hypothesized Mean Difference’.
Click on ‘OK’.

Excel Output:

From the output, the p value corresponding with two tail is 0.51.
