Expert Q8A Done A consumer advocate researches the length of life between two brands of refrigerators, Brand A and Brand B. He collects data (measured in years) on the longevity of 40 refrigerators for Brand A and repeats the sampling for Brand B. These data are measured in years. (You may find it useful to reference the appropriate table: z table or t table) b-1. Calculate the value of the test statistic. Assume that σ42-4.7 and ơB2-64. (Negative values should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.

Answer #1

Here

TA 17.075, σ2 4.7.12 A 40

and řB = = -40 ТВ 18.45, σ 6.4.nB

The test statistic can be written as

(TA - TB) which under H0 follows a standard normal distribution.

Now,

The value of the test statistic (17.075 - 18.45) obs =-1.57983 4.7 6.4 40 40
