Question list K (e). The reading speed of second grade students in a large city is approximately normal, with a mean of 90 words per minute (wpm) and a standard deviation of 10 wpm.

O Question 8 a) What is the probability a randomly selected student in the city will read more than 94 words per minute? The probability is O Question 9 (Round to four decimal places as needed.) (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 94 words per minute? Question 10 The probability is (Round to four decimal places as needed.) (c) What is the probability that a random sample of 22 second grade students from the city results in a mean reading rate of more than 94 words per minute? Question 11 The probability is (Round to four decimal places as needed.) Question 12 (d) What effect does increasing the sample size have on the probability? Provide an explanation for this result. A. Increasing the sample size increases the probability because o decreases as n increases. Question 13 O B. Increasing the sample size increases the probability because o increases as n increases. O C. Increasing the sample size decreases the probability because o decreases as n increases. Question 14 D. Increasing the sample size decreases the probability because o increases 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 21 second grade students was 92.3 wpm. What might you conclude based on this result? Select the correct choice and fill in the answer box in your choice below. Question 15 (Round to four decimal places as needed.)

After 10 weeks in the program, it was found that the mean reading speed of a random sample of 21 second grade students was 92.3 wpm. What might you conclude based on this result? Select the correct choice and fill in the answer box in your choice below. Question 14 (Round to four decimal places as needed.) A. A mean reading rate of 92.3 wpm is unusual since the probability of obtaining a result of 92.3 wom or more is . The new program is abundantly more effective than the old program. B. A mean reading rate of 92.3 wpm is not unusual since the probability of obtaining a result of 92.3 wpm or more is . The new program is not abundantly more effective than the old Question 15 program.
