1. Miller et al. (1988) wanted to see if Modified Reciprocal Teaching (MRT) would lead students to acquire better reading and writing skills than traditional instruction. They assigned students randomly to 1 of 2 groups, an MRT group, or a control group receiving traditional instruction. They gave a comprehension posttest to each group and compared the means. They reported the following:

"The comprehension scores of the MRT and Control group were significantly different, F (1, 44) = 15.38, p < .001."

Explain what this statement means in terms of statistical hypothesis testing (i.e., decisions with respect to the Null Hypothesis and the Alternate Hypothesis).
