In a normal distribution, what percentage of the population is within 1 SD of the mean? What about within 2 SD?
What will be an ideal response?
A measure of 1 SD above and 1 SD below the mean (±1 SD) includes 68 percent of the population, while ±2 SD includes 95 per-cent of the population. The 5th to 95th percentiles are nearly 2 standard deviations on either side of the mean.

The following utility function was calibrated based on an observed mode split of 84.9% private auto use and 15.1% bus use. Utility function: Uk = Ak – 0.10 X1 – 0.13 X2 – 0.12 X3 – 0.0045 X4 After implementing service improvements to the buses, the mode split changed to 81.6% private auto use and 18.4% bus use. Determine a value for the calibration constant for the bus mode that reflects this shift in mode split.
