The distance in kilometers, traveled to school by students may be modeled by a normal distribution with mean 7.5 and standard deviation 2.5, find w such that 10% of students travel less than w kilometers to school.

Step 1
To find the z-score corresponding to the 10th percentile, we can use a standard normal distribution table or a calculator. The z-score corresponding to the 10th percentile is approximately -1.28. Show more…

The distance that students drive to school is best modeled with a skewed right distribution that has a mean of 10 miles and a standard deviation of 2 miles. Suppose a sample of 100 students has been taken and the sample mean distance for the sample is calculated. Find the probability that the sample mean driving distance is less than 8 miles. .1587 .8413 Approximately 1 Approximately 0
