Help please, correct the wrong answers.

*Kindly Consider (use population standard deviation (divide by N) rather than the sample standard deviation (for which we used to divide by N-1))*

the given formula below (n-1) to be n only (as requested)

Standard deviation formula 2 SD = E (r; - rave) ? (-r n-1 r = actual rate of return r. avg = average rate of return (mean) n = number of time periods INI Problem 11-19 Diversification (L03) Here are the returns on two stocks.
