Unformatted text preview: Florida International University Department of Civil and Environmental Engineering EGN5455 – Numerical Methods in Engineering Assignment No. 4 – Due 29 Oct 2008 The bursting pressures of a sample of nominally identical set of metal tubes are found to be distributed as follows: Bursting pressure (kpsi) Observed frequency < 7.00 8 7.00 – 7.25 16 7.25 – 7.50 23 7.50 – 7.75 30 7.75 – 8.00 29 8.00 – 8.25 22 8.25 – 8.50 11 8.50– 8.75 5 > 8.75 1 The sample mean and standard deviation are 7.76 kpsi and 0.78 kpsi, respectively. Fit a normal probability density function to this distribution, and find the corresponding best (least squares) values for the and parameters. Determine the r2 for this nonlinear curve fit. Use either the shooting method, or the Newton‐Raphson method. ...
