b) Civil engineers have developed a 3D model to predict the response of jointed concrete pavements to temperature variations. To check this model, they measured the change in traverse strain on six different occasions and compared this to the modelled values. The table below was obtained, Change in Strain Field Modelled Date Measurement Measurement JUL 25 Aug 59 Aug 16 13 5 32 Sep 13 Jet 26 -39 NOVIB 71 Use the Summary output below to answer the following question Summary Output 4.4 (ili)Test whether the differences between the measurements are normally distributed. State your - hypothesis Ho : Data are normally distributed HA : Data are not normally distributed the test statistic - p-value, Decision ( Reject. Retain) - conclusion
