QUESTION 4 The reading speed of second grade students is approximately normal, with a mean of 88 words per minute (wprm) and a standard deviation of 10.31 wpm. Suppose a sample of 41 second grade students is selected from the populatión of students. (a) Find the standard error of the sampling distribution. Round your answer to 4 decimal places. (b) What is the probability that a random sample of 41 second grade students has a mean reading speed of at most 84.22 wpm? Round your answer to 4 decimal places. (c) What is the probability that in a random sample of 41 second grade students, the mean reading speed is more than 87.67 wpm? Round your answer to 4 decimal places.
