Answer:
Martha
Based on the data and assuming these trends continue,
Investment in Handy Prosthetics is preferred as it would give Martha a stable long-term investment.
Step-by-step explanation:
a) Data:
Handy El Lobo Malo
Prosthetics Incorporated
Standard deviation of stock prices = $1.05 $9.82
b) The above standard deviations measure the spread of the stock prices over their daily stock closing prices in one year. The Handy Prosthetics' stock does not fluctuate as much as the El Lobo Malo's stock. This reduced fluctuation in prices makes it a more stable investment than El Lobo Malo's stock. Therefore, Martha should prefer the Handy's stock to the El Lobo Malo's stock.
