The United States has an aging infrastructure as witnessed by several recent disasters, including the l-35 bridge failure in Minnesota. Most states inspect their bridges regularly and report their condition (on a scale from 17) to the public. Here are the condition numbers from a sample of 30 bridges 5.08 5.44 6.66 5.07 6.80 5.43 4.83 4.00 4.41 4.26 7.00 5.72 4.37 6.43 3.97 4.19 6.26 5.21 5.26 5.48 4.95 5.27 4.93 5.61 4.66 7.00 5.57 3.42 6.99 4.54 Find the sample mean and the sample standard deviation of these condition numbers. Round your answers to two decimal places (e.g. 98.76). i=5 S
