(c) What is the probability that a random sample of 28 second grade students from the city results in a mean reading rate of more than 97 words per minute? The probability is 0.0040. (Round to four decimal places as needed.) Interpret this probability. Select the correct choice below and fill in the answer box within your choice. A. If 100 independent samples of n = 28 students were chosen from this population, we would expect sample(s) to have a sample mean reading rate of exactly 97 words per minute. B. If 100 independent 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 97 words per minute. C. If 100 independent 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 97 words per minute.

The reading speed of second grade students in a large city is approximately normal, with mean of 92 words per minute (wpm) and standard deviation of 10 wpm. Complete parts (a) through (f). 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 less than 97 words per minute. (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 0.0307. (Round to four decimal places as needed.) Interpret this probability. Select the correct choice below and fill in the answer box within your choice. C A. If 100 independent samples of n = 14 students were chosen from this population, we would expect 3 sample(s) to have a sample mean reading rate of more than 97 words per minute. O B.
