Round your answer to 2 places after the decimal point, if necessary. 746.7 733.6 112.5 793.6 standard deviation – Question 7. Points possible: 1 This is attempt 1 of 1. Suppose you wish to invest money safely and are trying to decide between stock options in two companies. The average rates of return are the same for both companies but, one company has a much larger standard deviation of its rates of retum, a. Which company should you invest in? The company with the larger standard deviation The company with the smaller standard deviation b. Why is this the better choice? Question 8.

Last two figures are for positively skewed
data and negatively skewed data. Give thumb up. Thank you.
