Formula of confidence interval of one sample proportion:
=
=
=
Hence a 95 percent confidence interval for the proportion of all new websites that were anonymous is
b) May normality of p be assumed?
Condition for normality : np>10 and np(1-p)>10.
and
27.871 and 26.561063
Hence p is assumed to be normal since the condition is satisfied
Estimate:6000
You can use distributive property
"4 or less, just ignore, 5 or more go to the next door" so 3 is smaller than 5. So 510
