Question 10

In a test of the effectiveness of a new battery design, 16 battery-powered music boxes are randomly provided with either the old design or the new version. Hours of playing time before battery failure were as follows:

New battery type (hrs)	3.3	6.4	3.9	5.4	5.1	4.6	4.9	7.2
Old battery type (hrs)	4.2	2.9	4.5	4.9	5.0	5.1	3.2	4.0

Assuming normal populations with equal variances. The null and alternative hypotheses are used to determine whether the new battery could be better than the old design.

Compute the value of the test statistic,

		1.6413
		-1.6413
		1.6414
		-1.6414
