I've redone Stock B in part B 3 or 4 times and I keep getting the same answer. If you could show your work and help me figure out where I went wrong it would be appreciated, thank you!

Consider the following information: a. Calculate the expected return for the two stocks. (Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.) b. Calculate the standard deviation for the two stocks. (Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.) Answer is complete but not entirely correct
