Answer:
$5000*0.816 = $4082
Step-by-step explanation:
It's a strange question, but based on the statement and the question it sounds like it's a poisson distribution:
* For 3 days she was able to get 2 good shots (<em>typical of that time of the year</em>)
* Good shots happen randomly
* Each day is independent of another
Let's call 'p' the probability that she makes a good shot per day
Let's call 'n' the number of days Karen is taking shots.
So, if in 3 days he got 2 good shots and that is typical at that time of the year, then the expected value for the number of good shots (X) is:
For a Poisson distribution
So:
For a Poisson distribution the standard deviation is:
this is the standard deviation for the number of buentas taken.
So the standard deviation for income is the price of each shot per sigma
$5000*0.816 = $4082, which is the desired response.
