[c] What is the probability that a random sample of28 second grade students from the city results in a mean reading rate of more than 9? words per minute? The probability is (Round to four decimal places as needed.) Interpret this probability. Select the correct choice below and ll in the answer box with in your choice. [:1 A- If 100 different samples of n = 28 students were chosen from this population. we would expect sample(s) to have a sample mean reading rate of less than 9? words per minute. [:1 B- If 100 different samples of n = 28 students were chosen from this population. we would expect sample(s) to have a sample mean reading rate of exactly 9]" words per minute. [:1 C- If 100 different samples of n = 28 students were chosen from this population. we would expect sample(s) to have a sample mean reading rate of more than 9? words per minute. [d] What effect does increasing the sample size have on the probability? Provide an explanation for this result. [:1 A. Increasing the sample size increases the probability because 6)} decreases as n increases. [:1 B. Increasing the sample size increases the probability because 6)} increases as n increases. [:1 C. Increasing the sample size decreases the probability because tr; increases as n increases. [:1 D. Increasing the sample size decreases the probability because \"it decreases as n increases. [e] Ateacher 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 20 second grade students was '34 1 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.) [:1 33- Amean reading rate oi 94.i 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. [:3 3- Amean reading rate oi 94.i wpm is 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 abundantly more effective than the old program. [fl There is a 5% chance that the mean reading speed oi a random sample of 22 second grade students will exceed what value'?I There is a 5% chance that the mean reading speed of a random sample of 22 second grade students will exceed wpm (Round to two decimal places as needed.) (b) What is the probability that a random sample of 14 second grade students from the city results in a mean reading rate of more than 97 words per minute? The probability is. (Round to four decimal places as needed.) Interpret this probability. Select the correct choice below and fill in the answer box within your choice. O A. If 100 different samples of n = 14 students were chosen from this population, we would expect sample(s) to have a sample mean reading rate of exactly 97 words per minute. O B. If 100 different samples of n = 14 students were chosen from this population, we would expect sample(s) to have a sample mean reading rate of more than 97 words per minute. O C. If 100 different samples of n = 14 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.The 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.

(a) What is the probability a randomly selected student in the city will read more than 97 words per minute? The probability is. (Round to four decimal places as needed.) Interpret this probability. Select the correct choice below and fill in the answer box within your choice. O A. If 100 different students were chosen from this population, we would expect to read less than 97 words per minute. O B. If 100 different students were chosen from this population, we would expect to read exactly 97 words per minute. O C. If 100 different students were chosen from this population, we would expect to read more than 97 words per minute
