Question

Based on the equation: t₍₄₂₎= 5.15,p < 0.01,what is the right choice in the following? A)group 1= 21;group 2= 21 B)group 1= 22;group 2= 22 C)group 1= 20;group 2= 20 D)group 1=23;group 2= 23

Quizplus · Accepted Answer

From the equation t₍₄₂₎=5.15,p<0.01, we can determine that this is a two-sample t-test with unequal variances, and the sample sizes for both groups should be equal. Therefore, we can only choose from the options where the sample size for both groups is the same. Additionally, we cannot choose an odd number for the sample size since the formula involves multiplying by 42, which is an even number. Therefore, the only option that satisfies these criteria is B, where both groups have a sample size of 22.
