The United States has an aging infrastructure as witnessed by several recent disasters, including the I-35 bridge failure in Minnesota. Most states inspect their bridges regularly and report their condition (on a scale from 1-17) to the public. Here are the condition numbers from a sample of 30 bridges in New York State. 5.08 5.44 6.66 5.07 6.80 5.43 4.83 4.00 4.41 4.38 7.00 5.72 4.53 6.43 3.97 4.19 6.26 6.72 5.26 5.48 4.95 6.33 4.93 5.61 4.66 7.00 5.57 3.42 5.18 4.54 Find the quartiles and median of the data. Draw a box plot for the data. Should any points be considered as potential outliers?
