Consider a particle in a box surrounded by infinite walls - the so-called particle in a box problem. The box width is 1.0. Which of the 5 wavefunctions can describe the particle in that box? (Hint: recall that wavefunctions need to be differentiable (i.e. need to produce a nice derivative), and cannot penetrate into and beyond the size of the box). Explain your answer. Rank the allowed wavefunctions in order of increasing energy.

In one study on physical activity, participants used accelerometers and a seven-day travel log to monitor their physical activity. Researchers used the data from each participant to quantify the amount of daily physical activity and to classify each participant as a nontransit user, or a low, mid, or high-frequency transit user. Here is a summary of physical activity in minutes per day broken down into walking and non-walking activities. One-way ANOVA was used to compare the groups across each activity. Activity Mean Lower Higher P-value Walking 21.84 25.48 34.4 36.5 <0.001 Non-walking 16.0 13.5 11.9 15.2 0.24
