The use of the interval

requires a large sample. For each of the following combinations of n and p^, indicate whether the sample size is large enough for use of this interval to be appropriate.
a. n = 50 and p^ = .30
b. n = 50 and p^ = .05
c. n = 15 and p^ = .45
d. n = 100 and p^ = .01
e. n = 100 and p^ = .70
f. n = 40 and p^ = .25
g. n = 60 and p^ = .25
h. n = 80 and p^ = .10
