Question

Problem 1 One of the advantages that concrete structures have over steel structures is fire resistance (which is to say, steel becomes weak when heated). The time, T, that it takes a steel girder to reach certain temperature (where its strength becomes too low to support its load) in a fire is, however, random. Suppose that for design code development, the following data have been gathered on the time T in hours: 0.736, 0.863, 0.865, 0.913, 0.915, 0.937, 0.983, 1.007, 1.011, 1.064, 1.109, 1.132, 1.140, 1.153, 1.253, 1.394 (a) Compute the values of the sample mean and the sample median by hand. (b) By how much could the smallest sample observation be increased without affecting the value of the sample median? (c) By how much could the smallest sample observation be increased without affecting the value of the sample mean? (d) Compute the values of the first quartile, third quartile, interquartile range, lower fence
