Answer #1

Answer is 10%

Expected Return = 8%
Standard Deviation = 1%

95% Confidence Interval = Expected Return - 2 * Standard Deviation, Expected Return + 2 * Standard Deviation
95% Confidence Interval = 8% - 2 * 1%, 8% + 2 * 1%
95% Confidence Interval = 8% - 2%, 8% + 2%
95% Confidence Interval = 6%, 10%

Therefore, next year’s return will not be above 10%
