What is the probability of finding a particle in a box of length LL in the region between x=L/4x=L/4 and x=3L/4x=3L/4 when the particle is in the ground level? (Hint: Integrate |ψ(x)|2dx|ψ(x)|2dx, where ψψ is normalized, between L/4L/4 and 3L/43L/4.)

Robert plans to make a box-and-whisker plot of the following set of data. 27, 14, 46, 38, 32, 18, 21 find the lower quartile, the median, and the upper quartile of the set? lower quartile: 19.5; median: 29.5; upper quartile: 42 lower quartile: 14; median: 27; upper quartile: 46 lower quartile: 18; median: 27; upper quartile: 38 lower quartile: 16; median: 29.5; upper quartile: 42
