A teacher instituted a new reading program at school. After 10weeks in the​ program, it was found that the mean reading speed ofa random sample of 20 second grade students was
94.4 wpm. What might you conclude based on this​ result? Selectthe correct choice below and fill in the answer boxes within yourchoice.
​(Type integers or decimals rounded to four decimal places as​needed.)
A. A mean reading rate of 94.4 wpm is not unusual since theprobability of obtaining a result of 94.4 wpm or more is ____. Thismeans that we would expect a mean reading rate of 94.4
or higher from a population whose mean reading rate is 92 in____ of every 100 random samples of size n=20 students. The newprogram is not abundantly more effective than the old program.
B. A mean reading rate of 94.4 wpm is unusual since theprobability of obtaining a result of 94.4 wpm or more is ____. Thismeans that we would expect a mean reading rate of 94.4
or higher from a population whose mean reading rate is 92 in____ of every 100 random samples of size n=20 students. The newprogram is abundantly more effective than the old program.
