A teacher instituted a new reading program at school. After 10 weeks in the program, it was found that the mean reading speed of a random sample of 19 second grade students was 91.7 wpm. What might you conclude based on this result? A) A mean reading rate of 93.9 wpm is unusual since the probability of obtaining a result of 93.9 wpm or more is . The new program is abundantly more effective than the old program.
B) A mean reading rate of 93.9 wpm is not unusual since the probability of obtaining a result of 93.9 wpm or more is. The new program is not abundantly more effective than the old program.
