E Homework: Ch 8 HW: Sampling Distribution Question 3, 8.1.21-T > Hw Score: 85.35%. 16.22 or19 paints FartEof'a @ Points. _. oft The reading speed of second grade students in a large city is approximately normal, with a mean of 38 words per minute (worn) and a standard deviation of10 wpin. Complete parts (a) through (t). :P-VB- H100 dierent students were rhosen from this pupuiation, we would expect 2? to read more than 54 words per minute. ' (3- H100 dierent students were chosen from this pupuiation, we would expect to read exactly 94 words per minute [b] What is the probability That a random sample ot10 second grade students from the city results in a mean reading rate of more than 04 words per minute? The probability is 0.0289'. (Round to tour decimal places as needed.) Interpret this probability. Select the correct choice below and il in the answer box within your choice. vA- H100 independent samples of i'l =10 students were chosen from this population. we would expect 3 sample[s) to have a sample mean reading rate of more than 94 words per minute. 3- H100 independent samples of i'l =10 students were chosen from this population. we would expect sampie[s) to have a sample mean reading rate of iess than 94 words per minute. (3- H100 independent samples of i'l =10 students were chosen from this population. we would expect sampie[s) to have a sample mean reading rate of exactiy 94 words per minute. [c] What is the probability that a random sample of 20 second grade students from the city resuits in a mean reading rate of more than 94 words per minute? The probability is 0.003? (Round to tour decimal places as needed.) Interpret this probability. Select the correct choice below and il in the answer box within your choice.
