(b) What is the probability that a random sample of 11 second grade students from the city results in a mean reading rate of more than 94 words per minute? The probability isO: (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 independent samples of n = 11 students were chosen from this population, we would expect sample(s) to have a sample mean reading rate of less than 94 words per minute. O B. If 100 independent samples of n = 11 students were chosen from this population, we would expect sample(s) to have a sample mean reading rate of exactly 94 words per minute. O C. If 100 independent samples of n = 11 students were chosen from this population, we would expect sample(s) to have a sample mean reading rate of more than 94 words per minute.
