Based on the following informations, calculate the expected returns and standard deviations:

Depression, $0\mathrm{.}15$ probability of state, $-0\mathrm{.}105$ rate of return

Recession, $0\mathrm{.}30$ probabaility of state, $0\mathrm{.}059$ rate of return

Normal, $0\mathrm{.}45$ probability of state, $0\mathrm{.}130$ rate of return

Boom, $0\mathrm{.}10$ probability of state, $0\mathrm{.}211$ rate of return
