he reading speed of second grade students in a large city is approximately normal with a mean of 92 words per minute (wpm) and a standard deviation of 10 wpm. Complete parts (a) through () ick here to view the standard normal distribution table (gage 1. ck here to view the standard normal distribution table feage 2 B. # 100 dferent samples of n= 13 students were chosen from this population, we would expect sample(s) to have a sample mean reading rate of less than 97 words per minute. If 100 different samples of n= 13 students were chosen from this population, we would expect 4 sample(s) to have a sample mean reading rate of more than 97 words per minute )What is the probability that a random sample of 26 second grade students from the city results in a mean reading rate of more than 97 words per minute? me probability is 0.0054 tound to four decimal places as needed) terpret this probability. Select the corect choice below and fil in the answer box within your choice A. IF 100 diferent samples of n=26 students were chosen from this population, we would expect samplejs) to have a sample mean reading rate of exactly 97 words per minute B. # 100 different samples of n= 26 students were chosen from this population, we would expect sample(s) to have a sample mean reading rate of less than 97 words per minute If 100 dfferent samples of n= 26 students were chosen from this population, we would expect 1 sample(s) to have a sample mean reading rate of more than 97 words per minute What effect does increasing the sample size have on the probability? Provide an explanation for this result A. Increasing the sample size decreases the probability because o, decreases as n increases B. Increasing the sample size increases the probability because a; decreases as n increases. OC. Increasing the sample size decreases the probability because o, increases as n increases. D. Increasing the sample size increases the probability because o, increases as n increases. JA teacher instituted a new reading program at school. Ater 10 weeks in the program, it was found that the mean reading speed of a random sample of 20 second grade students was 94 1 wpm. What might you conclude based on this result? Select the correct choice below and l in the answer baxes within your choi ype integers or decimals rounded to four decimal places as needed) A. Amean reading rate of 94.1 wpm is unusual since the probablity of obtaining a result of 94.1 wpm or more is This means that we would expect a mean reading rate of 94.1 or higher from a population whose mean reading rate is 92 in of every 100 random samples of size n= 20 students. The new progra abundantly more effective than the old program. OB. Amean reading rate of 94.1 wpm is not unusual since the probability of obtaining a result of 94.1 wpm or more is This means that we would expect a mean reading rate of 94.1 or higher from a population whose mean reading rate is 92 in of every 100 random samples of size n= 20 students. The new program is not abundantly more effective than the old program
