The reading speed of second grade students in a large city is approximately normal, with a mean of 91 words per minute (wpm) and a standard deviation of 10 wpm. 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). (d) What effect does increasing the sample size have on the probability? Provide an explanation for this result. A. Increasing the sample size decreases the probability because o, decreases as n increases. B. Increasing the sample size increases the probability because o; increases as n increases. C. Increasing the sample size decreases the probability because o- increases as n increases. D. Increasing the sample size increases the probability because o: decreases as n increases. (e) A teacher instituted a new reading program at school. After 10 weeks in the program, it was found that the mean reading speed of a random sample of 19 second grade students was 93.8 wpm. What might you conclude based on this rese Select the correct choice below and fill in the answer boxes within your choice
