I think the answer is Letter C - 0.032.
Given: p - 0.1; n - 90
Required: standard deviation of the sample proportion
Solution: To get the standard deviation of the sample proportion, we will use this formula - std = √p (1 - p) / n Replace the variables with the given values, then simplify.
std = √0.1 (1 - 0.1) / 90
std = √0.09 / 90
std = √0.001
std = 0.032
Answer:
The copy machine makes 32 copies per minute.
Step-by-step explanation:
Given that a copy machine makes 136 copies in 4 minutes and 15 seconds, to determine how many copies does it make per minute, the following calculation must be performed:

136 / 4.25 = X
32 = X
Therefore, the copy machine makes 32 copies per minute.
