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 1–7) to the public. Here are the condition numbers from a sample of 30 bridges in New York State: 5.00 5.44 6.66 5.07 6.80 5.43 4.83 4.25 4.41 4.36 7.02 5.72 4.58 6.43 3.97 4.32 6.26 6.82 5.26 5.47 4.96 6.33 4.93 5.61 4.95 7.01 5.57 3.42 5.18 4.51 Choose the correct steam-and-leaf diagram. Do any of the bridges appear to have unusually good or poor ratings? If so, compute the mean with and without these bridges.
