Suppose that we have data on the market portfolio corresponding with associated expected return is e_M=13.9 and standard deviation s_M=10. There is a risk free asset with expected return of r_f=2.9. The investor has a tolerance to risk measured by t=1.3 and has a wealth normalised by 1. The investor wishes to build an optimal portfolio using the market portfolio with proportion x and the risk free asset. He has an expected utility of EU=e_p-s_p²/t where e_p is the expected return and s_p² are the expected return and variance on the portfolio constructed with the risk free asset and the market portfolio.

Calculate the optimal choice of portfolio x between the market portfolio and the risk free asset. (Round your answer to 1 decimal.)
