Complete parts (a) through (f). here to view the standard normal distribution table (page 1). k here to view the standard normal distribution table (page 2). B. Increasing the sample size increases the probability because of decreases as n increases. C. Increasing the sample size decreases the probability because of increases as n increases. D. Increasing the sample size increases the probability because of increases as n increases. ) 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 93.6 wpm. What might you conch ased 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 93.6 wpm is unusual since the probability of obtaining a result of 93.6 wpm or more is This means that we would expect a mean reading rate of 93.6 or higher from a population whose reading rate is 91 in of every 100 random samples of size n = 19 students. The new program is abundantly more effective than the old program. B. A mean reading rate of 93.6 wpm is not unusual since the probability of obtaining a result of 93.6 wpm or more is 0.1292 . This means that we would expect a mean reading rate of 93.6 or higher from a population whose mean reading rate is 91 in 13 of every 100 random samples of size n = 19 students. The new program is not abundantly more effective than the old program. (f) There is a 5% chance that the mean reading speed of a random sample of 21 second grade students will exceed what value? There is a 5% chance that the mean reading speed of a random sample of 21 second grade students will exceed wpm. (Round to two decimal places as needed.)
