Question

A factorial experiment was designed to test for any significant differences in the time needed to perform English to foreign language translations with two computerized language translators. Because the type of language translated was also considered a significant factor, translations were made with both systems for three different languages: Spanish, French, and German. Use the following data for translation time in hours.

	Language
	Spanish	French	German
System 1	8	9	15
	12	13	19
System 2	6	15	16
	10	17	22

Test for any significant differences due to language translator system (Factor A), type of language (Factor B), and interaction. Use .

Complete the following ANOVA table (to 2 decimals, if necessary). Round your p-value to 4 decimal places.

Factor A	8.33	1	8.33	0.96	0.3650
Factor B	162	2	81	9.35	0.0143

>> The p-value for Factor A is - greater than .05

>> Conclusion with respect to Factor A: Factor A is not significant.

>> The p-value for Factor B is - Select your answer - between .0125 and .025

>> Conclusion with respect to Factor B: Factor B is significant. [Only if your alpha level is greater than 0.02, otherwise not significant for alpha = 0.01

>> The p-value for the interaction of factors A and B is - greater than .05

>> Conclusion with respect to the interaction of Factors A and B: The interaction of factors A and B is not significant.
