T Test Example. So the hypothesis that the statistics of the two samples are significantly different can t be rejected. For example if the mean of group 1 is 10 and the mean of group 2 is 4 the difference is 6.

We have the potato yield from 12 different farms. You can see in the equation that when the two groups are equal the difference and the entire ratio also equals zero. Gather the sample data.
T test example if a sample of 10 copper wires is found to have a mean breaking strength of 527 kgs is it feasible to regard the sample as a part of a large population with a mean breaking strength of 578 kgs and a standard deviation of 12 72 kgs.
A very simple example. Suppose we want to know whether or not the mean weight between two different species of turtles is equal. X 21 5 24 5 18 5 17 2 14 5 23 2 22 1 20 5 19 4 18 1 24 1 18 5 test if the potato yield from these farms is significantly better than the standard yield. Compute the appropriate t test for the data provided below.
