A manufacturer of soft dog treats establishes that,on average,13.5% of each treat contains "crude protein",with a standard deviation of $\sigma$
= 0)1%.When the process machine is properly calibrated,then this value is maintained,but uncontrollable factors such as moisture levels can alter the crude protein percentage.For quality control purposes,the manufacturer wishes to estimate the mean crude protein percentage to within 0.025% of its true value with a 99% confidence.If the percentage of "crude protein" is normally distributed,what sample size should be used?
A)677
B)107
C)35
D)27
E)11
