Answer:
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:
We have to calculate the probabilty that the sample proportion will be between 0.25 and 0.33.

Answer:
radius = √5 = 2.24 to nearest hundredth.
Step-by-step explanation:
(x + 3)^2 + (y + 3)^2 = 5 comparing with the standard form
(x - h)^2 + (y - k)^2 = r^2
-h = 2 so h = -3, -k = 3 so k = -3.
r^2 = 5 so r = √5.
