Statıstıcs Iı Deneme Sınavı Sorusu #1058123

For sample one the sample size is 10, mean is 4.5, and standard deviation is 1. For sample two the sample size is 12, mean is 3.4, and standard deviation is 1.2 and (µ1 -µ2 ) is considered to be equal to 0. What is the test statistics for the given values?

Yanıt Açıklaması:

Since the sample sizes are smaller than 30 we will use this formula. The numerator is equal to (4.5 - 3.4) - 0 = 1.1. The denominator is equal to [(1)²/10] +[(1.2)²/12] = 0.1+0.12 = 0.22. these results would yield to a test statistic of z=1.1/0.22 = 5

The answer is B.
