Explanation of Solution

The core plus mathematics program (CPMP) is an innovative approach to teaching mathematics. After field test in high schools over a three-year period, researchers compared the performances of CPMP students with those taught using traditional curriculum. The data given in the question is:

Math Program	n	Mean	SD
CPMP	320	57.4	32.1
Traditional	273	53.9	28.5

Thus, we conclude from the following given information that the students who chooses the CPMP are more than the students who adopt the traditional program. Also, the mean average score obtained by the students of CPMP is more than the average score obtained by the students of traditional program. Bu the variation in the scores of the students of CPMP is higher than the variation of the sores of the students of traditional program. Therefore, we can say that the CPMP is significantly more efficient than the traditional program.
