Answer:

C) 0.45

Step-by-step explanation:

Given that a population mean is 0.45, standard deviation is 0.001 and margin of error stands at 0.5% we have the following

0.45 + 0.001 = 0.451

Population mean with standard deviation is 0.451.

0.451 * 0.5% = 0.448745

We now reduce the number to two decimals and get the final marigin of error

0.45 as result
