There are two methods A and B for studying the latent heat of
ices. The following are the collected data of the heat absorption
when the ices absorbed heat and their temperature increased from
initial -0.72℃ to temperature 0℃: Method A : 79.98, 80.04, 80.02,
80.03, 80.03, 80.04, 80.04 79.97, 80.05, 80.03, 80.02, 80.00, 80.02
Method B: 80.02, 79.94, 79.97, 79.98, 79.97, 80.03, 79.95, 79.97
Assume these data follow normal distribution with equal variance.
Test the hypothesis H0“the mean ?...
