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 18 second grade students was 92.3 wpm. What might you conclude based on this result? Select the correct choice below and fill in the answer boxes within your choice. (Type integers or decimals rounded to four decimal places as needed.) A. A mean reading rate of 92.3 wpm is unusual since the probability of obtaining a result of 91.6 wpm or more is ______. This means that we would expect a mean reading rate of 92.3 or higher from a population whose mean reading rate is 90 in _____ of every 100 random samples of size n =18 students. The new program is abundantly more effective than the old program. OR B. A mean reading rate of 92.3 wpm is not unusual since the probability of obtaining a result of 92.3 wpm or more is _____. This means that we would expect a mean reading rate of 91.6 or higher from a population whose mean reading rate is 90 in ______ of every 100 random samples of size n = 18 students. The new program is not abundantly more effective than the old program.

(Type integers or decimals rounded to four decimal places as needed.)
A. A mean reading rate of 92.3 wpm is unusual since the probability of obtaining a result of
91.6 wpm or more is ______. This means that we would expect a mean reading rate of 92.3 or higher from a population whose mean reading rate is 90 in _____ of every 100 random samples of size n =18 students. The new program is abundantly more effective than the old program.
OR
B. A mean reading rate of 92.3 wpm is not unusual since the probability of obtaining a result of 92.3 wpm or more is _____. This means that we would expect a mean reading rate of 91.6 or higher from a population whose mean reading rate is 90 in ______ of every 100 random samples of size n = 18 students. The new program is not abundantly more effective than the old program.
