The probability that the proportion of books checked out in a sample of 412 books would differ from the population proportion by less than 4% is P=0.9255.
Step-by-step explanation:
The population's proportion is
If we take a sample of 412 books (n=412), we have a standard deviation of the sampling distribution of:

So,first step is to write
Now we start from inner paranthesis
,we need to first find value of
