Structural Engineers in an iron manufacturing company describe the results of deformation on the natural frequency of alloys made from composite material. Five such delaminated alloys were subjected to loads, and the resulting frequencies (in hertz) were as follows: 230.66, 233.05, 232.58, 229.48, 232.58 Compute a 90% prediction interval on the diameter of the natural frequency of the next beam of this type that will be tested. Ο a.230.2 <μ< 233.1 b. None of the above O c. 228.1 < Xn+13235.2 O d. The 90% prediction interval is wider than the 90% confidence interval on the population mean
