A company that manufactures electronic components wants to evaluate the following hypothesis test, using a level of significance of 0.1.
A random sample of 15 components was taken; 9 were tested at 80° F (X1), and 6 were tested at 120° F (X2). Suppose the resulting test statistic is 1.3 and test statistic has t distribution with 13 degree of freedom.
