Students at a Southern California university are complaining about lack of housing near campus, forcing many to commute long distances. A university study reported commute distances for 48 students in a histogram. The standard deviation of the sample distances was estimated based on the histogram data.

1. Students at a major unlversity in Southern California are complaining about a serious housing
crunch. They say that many of the unlversity's students have to commute too far to school
because there is not enough housing near campus. University officials perform a study, which is
reported in the school newspaper, The report contains the following histogram summarizing the
commute distances for a sample of 48 students at the university. Based on this histogram,
estimate the standard deviation of the sample of 48 distances. Carry your intermediate
computations to at least four decimal places, and round your answer to at least one decimal
place. (If necessary, consult a list of fomulas.)
