Question

Several students were tested for reaction times​ (in thousandths of a​ second) using their right and left hands.​ (Each value is the elapsed time between the release of a strip of paper and the instant that it is caught by the​ subject.) Results from five of the students are included in the graph to the right. Use a 0.02
significance level to test the claim that there is no difference between the reaction times of the right and left hands.

what is the t value?

what is the critical value?

Answer 1

In Minitab, Stat-basic statistics-two sample t for the mean.

Select each sample is in its own column and enter c1 and c2 in there samples. In options enter 98% confidence interval.

The output is given below:

The t value is -0.74.

The critical value is given as, .

The t value does not lie in the critical region. fail to reject the null hypothesis. There is no difference between the reaction times of the right and the left hands.
