The reading speed of second grade students in a large city is approximately normal, with a mean of 88 words per minute (wpm) and a standard deviation o through (f). O B. If 100 different students were chosen from this population, we would expect to read exactly 93 words per minute. O C. If 100 different students were chosen from this population, we would expect 31 to read more than 93 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 93 words per minute The probability is.

Question
The reading speed of second grade students in a large city is approximately normal, with a mean of 88 words per minute (wpm) and a 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 93 words per minute. O C. If 100 different students were chosen from this population, we would expect 31 to read more than 93 words per minute. A (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 93 words per minute? The probability isU. (Round to four decimal places as needed.)
