Question

Question 33 (1 point) d An important factor in selecting software for word-processing and database management systems is the time required to learn how to use the system. To evaluate three file management systems, a firm designed a test involving word processing operators. Since operator variability was believed to have an impact, each of the operators was trained on all three of the file management systems. D.F MS P- VALUE System 0.000019 103.33 2 51.67 56.36 17.63 Operator 0.000494 64.67 4 16.17 ERROR 7.33 0.92 TOTAL 175.33 14 ) no differences exist differences exist among operators only differences exist among systems only.

Explanation / Answer

Ans:

Assume significance level=0.05

As,p-value for both operators and systems is less than 0.05,we reject the null hypothesis and we can conclude that difference exist among both operators and systems.
