Complete parts (a) through (1). (a) What is the probability a randomly selected student in the city will read more than 97 words per minute? The probability is 0.2743 . (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 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 27 to read more than 97 words per minute. (b) What is the probability that a random sample of 10 second grade students from the city results in a mean reading rate of more than 97 words per minute? The probability is 0.0289. 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 = 10 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 = 10 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.
