The population variances for two samples are 2 and 5, the difference of the sample means for these two samples is 3, and the sample sizes are 100 and 500, respectively. For the given values what is the test statistic?


10

20

40

50

Yanıt Açıklaması:

the test statistic for two sample tests of means when their population variances are known The formula gives the test statistic for two sample tests of means when their population variances are known. since x1 - x2 =3, and the denominator of the formula can be written as {[(2)2/100]+[(5)2/500]}1/2 which would be equal to 0.3. This would yield to z=3/(0.3) = 10

The answer is A
