Answer:
The mean of the data is of 3.7143%.
Step-by-step explanation:
Mean of the data:
Sum of all returns divided by the number of returns.
Returns:
6% 5% -2% 10% 3% 8% -4%
7 returns.
Sum: 6 + 5 - 2 + 10 + 3 + 8 - 4 = 26%
Mean: 26%/7 = 3.7143%
The mean of the data is of 3.7143%.

Answer:
The correct option is A....
Step-by-step explanation:
We have a table of x,y pairs. To compute the slope we can use any two pairs, say the first two, and plug them into our formula:
m = y2-y1 / x2-x1
m = 5-13/ 0-(-2)
m = -8/0+2
m = -8/2
m = -4
We can check this answer by using a different pair: Take the last two pairs.
m = -27-(-15)/ 8-5
m = -27+15/3
m = -12/3
m = -4
Thus the slope is -4
The correct option is A....
