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 w Complete parts (a) through (f). Click here to view the standard normal distribution table (page 1). Click here to view the standard normal distribution table (page 2). CA. If 100 different students were chosen from this population, we would expect to read less than 96 words per minute. B. If 100 different students were chosen from this population, we would expect 34 to read more than 96 words per minute. O C. If 100 different students were chosen from this population, we would expect to read exactly 96 words per minute. (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 96 words per minute? The probability is IN (Round to four decimal places as needed.)
