Question 1194300: The following are measurements of the heat-producing capacity (in millions of calories per ton) of random samples of five specimens each of coal from two mines:
Mine 1: 8,380 8,210 8,360 7,840 7,910 Mine 2: 7,540 7,720 7,750 8,100 7,690
Use the 0.05 level of significance to test whether the difference between the means of these two samples is significant.
