Question 1169314: Suppose we have a binomial experiment in which success is defined to be a particular quality or attribute that interests us.
(a) Suppose n = 25 and p = 0.34. (For each answer, enter a number. Use 2 decimal places.)
n·p =
n·q =
Can we approximate p̂ by a normal distribution? Why? (Fill in the blank. There are four answer blanks. A blank is represented by _____.)
_____, p̂ _____ be approximated by a normal random variable because _____ _____.
first blank
Yes
No
second blank
can
cannot
third blank
n·p exceeds
n·p and n·q do not exceed
n·q does not exceed
both n·p and n·q exceed
n·q exceeds
n·p does not exceed
fourth blank (Enter an exact number.)
What are the values of μp̂ and σp̂? (For each answer, enter a number. Use 3 decimal places.)
μp̂ = mu sub p hat =
σp̂ = sigma sub p hat =

np=8.50
nq=16.50
no
cannot
do not exceed 10 (if you use 10 as a cut off point, which is reasonable).
the mean is np hat =8.500
n sigma hat is np(1-p) for variance and that is 5.44; sd is sqrt (V) and sd is sqrt(5.44)=2.332
