In terms of Porfolio Variance calculation/formula of 0.02819 your computation is different than mine of 0.8733428592 based on the formula you provided. Can you explain on how did you get the 0.02819 portfolio variance

Consider a population proportion p = 0.20. a. What are the expected value and the standard error for the sampling distribution of the sample proportion with n = 20 and n = 58? Note: Round the standard error to 4 decimal places. Answer is complete and correct. n Expected value Standard error 20 58 0.20 0.20 0.0894 0.0525 b. Can you conclude that the sampling distribution of the sample proportion is approximately normally distributed for both sample sizes? Yes, the sampling distribution of the sample proportion is normally distributed for both sample sizes. No, the sampling distribution of the sample proportion is not normally distributed for either sample size. No, only the sample proportion with n = 20 will have a normal distribution. No, only the sample proportion with n = 58 will have a normal distribution. c. If the sampling distribution of the sample proportion is normally distributed with n = 20, then calculate the probability that the sample proportion is between 0.18 and 0.20.…
