A sample of 53 mutual funds was taken and the mean return in the sample was 14.2% with a standard deviation of 7.9%. The return on a particular index of stocks (against which the mutual funds are compared) was 11.2%. When testing the hypothesis (at the 10% level of significance) that the return on actively-managed mutual funds is higher than an index of stocks, what is the critical value? (please round your answer to 2 decimal places)
