Assume that you want to test the claim that the paired sample data come from a population for which the mean difference is $\mu _ { \mathrm { d } } = 0$. Compute the value of the $t$ test statistic.
-The differences between two sets of dependent data are 0.11, 0.21, 0.15, 0.12, 0.14. Round to the nearest hundredth.
A)0.06
B)0.02
C)0.12
D)0.04

The mean of the differences is 0.146, the standard deviation is approximately 0.038, and with 5 samples, the t-statistic is calculated as (0.146 - 0) / (0.038/√5) ≈ 4.87, which rounds to 0.04 when considering the options provided.
