Quiz: Ch 8 Qu' Samp ' 9 Distribution Question 1 of1 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'll] wpm Complete parts (a) through (f) [c] What is the probability that a random sample of 20 second grade students trom the cit).I results in a mean reading rate of more than 98 words per minute? The probability is . (Round to four decimal places as needed.) Interpret this probability. Select the correct choice below and ll in the answer box within your choice. O A. It 100 independent samples of n :20 students were chosen from this population. we would expect samplets) to have a sample mean reading rate of exactly 93 words per minute. O B' It' 100 independent samples of n =20 students were chosen from this population, we would expect samples) to have a sample mean reading rate of more than 98 words per minute O C It' 100 independent samples of n =20 students were chosen from this population. we would expect samplets) to have a sample mean reading rate of Ias than 98 words per minute. [d] What effect does increasing the sample size have on the probabiiity'? Provide an explanation for this result. 0 Ar Increasing the sample size decreases the probability because "it increases as n increases 0 B. Increasing the sample size increases the probabiiity because 0); increases as n increases. 0 C. Increasing the sample size increases the probabiitly because or); decreases as n increases 0 Dr Increasing the sample size decreases the probability because 6; decreases as n increases
