Question

Two types of flares are tested for their burning times ( in minutes ) and sample results are
given below:

Brand X: n1= 35     x1= 19.4       s1 = 1.4
Brand Y: n2 = 40     x2 = 15.1     s2 = 0.3

Refer to the sample data to test the claim that the two populations have equal means. Use a 0.05 significance level.
