Multiple Choice

Use the following information for questions:
It is known that for right-handed people, the dominant (right) hand tends to be stronger. For left-handed people who live in a world designed for right-handed people, the same may not be true. To test this, muscle strength was measured on the right and left hands of a random sample of 15 left-handed men and the difference (left - right) was found. The alternative hypothesis is one-sided (left hand stronger) . The resultingt-statistic was 1.80.
-Assuming the conditions are met, based on the t-statistic of 1.80 the appropriate decision for this test using $\alpha$ = 0.05 is:

A) df = 14, so p-value < 0.05 and the null hypothesis can be rejected.
B) df = 14, so p-value > 0.05 and the null hypothesis cannot be rejected.
C) df = 28, so p-value < 0.05 and the null hypothesis can be rejected.
D) df = 28, so p-value > 0.05 and the null hypothesis cannot be rejected.
