You observe a portfolio for five years and determine that its average return is 11.7% and the standard deviation of its returns in 19.5%. Would a 30% loss next year be outside the 95% confidence interval for this portfolio? The low end of the 95% prediction interval is %. (Enter your response as a percent rounded to one decimal place.) O A. Yes, you can be confident that the portfolio will not lose more than 30% of its value next year. This is because the low end of the prediction interval is less than -30% OB. Yes, you can be confident that the portfolio will not lose more than 30% of its value next year. This is because the low end of the prediction interval is greater than - 30%. O C. No, you cannot be confident that the portfolio will not lose more than 30% of its value next year. This is because the low end of the prediction interval is greater than - 30%. OD.

At the beginning of 2007 (the year the iPhone was introduced), Apple's beta was 1.1 and the risk-free rate was about 3.9%. Apple's price was $80.42. Apple's price at the end of 2007 was $198.32.
