Answer: 0.0221
Step-by-step explanation:
We know that the formula to find the standard deviation of the sample proportion is :
, where p = proportion of success.
n= sample size.
As per given , we have
p=0.58
n= 500
Then, the standard deviation of the sample proportion in this situation would be :
Hence, the standard deviation of the sample proportion in this situation is 0.0221 .

Answer:
Step-by-step explanation:
To find many more pounds of apples Kimane and his friend needs to get, we first need to find out how many pounds of apples they picked together.
Kimane =
Friend =
We add them together to find out how many pounds of apples they currently have.
Total Pounds =
Just to make the equation clearer, we separate the whole numbers from the fractions.
Now since we cannot add the 2 fractions directly since they have different denominators, we need to convert the into a fraction with the same denominator.
We multiply both the numerator and denominator by 2 to have the same denominator.
So now we have:
Now that we know how many pounds Kimane and his friend collected, we simply subtract 20 and the total amount Kimane and his friend had already collected.
So Kimane and his friend still need to get more pounds of apples to get 20 pounds of apples.
