For the next three questions, ASSUME that the one-year holding period returns (HPRs) for Tesla are:

{-20%; +60%; +10%; -6%; +520%}

These are close to but are not exactly equal to Teslas actual annual HPRs.

Answer format: e.g. XX.X% = XX.X, 12.3% = 12.3 (no % sign, only 1 decimal place)

The arithmetic mean of the one-year HPRs for Tesla is:

The geometric mean of the annual one-year HPRs for Tesla is:

(Note: For this question, you must use an algebraic solution, because the HPRs provided above are approximations, not the exact values. If you use your function keys and prices from the table, you will obtain a close but an incorrect answer.)

The sample standard deviation of the annual one-year HPRs for Tesla is:

(Note: Calculated using the arithmetic mean if you are using algebra)
