The 95.4 percent range for the equity risk premium can be calculated using the formula for a confidence interval around the mean, which is mean ± (2 * standard deviation) for approximately 95% confidence. Here, it's 5.49 ± (2 * 11.46), which equals -17.43 to 28.41. However, none of the options match this calculation directly, suggesting a misunderstanding in the question's interpretation. Given the options, the closest approach to applying the concept would be recognizing an error in calculation and instead applying a more nuanced understanding of the distribution or a typo in the original calculation. The correct choice, based on the options provided and assuming a possible misinterpretation in applying the standard deviation directly, would be option D, as it seems to be the closest to what might be expected from a range around the mean, despite the calculation error. This choice assumes a conceptual understanding that the range should encompass values around the mean (5.49%) and acknowledges an error in the direct application of the formula provided.
