Consider a particle moving in the potential V(x) rectangular region of depth Vo, and width a, in which the particle can be bound. These parameters are related to the mass m of the particle in such a way that the lowest allowed energy E1is found at an energy about V0/4 above the "bottom." Use qualitative argu- ments to sketch the approximate shape of the corresponding eigenfunction t/i 1(x).

1. why is a frequency distribution useful? it allows researchers to see the "shape" of the data. it tells researchers how often the mean occurs in a set of data. it can visually identify the mean. it ignores outliers. 2. the is defined by its mean and standard deviation alone. normal distribution frequency distribution median distribution marginal distribution 3. approximately % of the data in a given sample falls within three standard deviations of the mean if it is normally distributed. 95 68 34 99 4. a data set is said to be if the mean of the data is greater than the median of the data. normally distributed frequency distributed right-skewed left-skewed
