Suppose we have a binomial experiment in which success is defined to be a particular quality or attribute that interests us.
(b) Suppose
n
= 25 and
p
= 0.15. Can we safely approximate p̂ by a normal distribution? Why or why not?
(Yes/No) , p̂ (can/cannot) be approximated by a normal random variable because ____(np and nq do not exceed, nq exceeds, nq does not exceed, np does not exceed, nq does not exceed, np exceeds, both np and nq exceed) ________ (fill in blank)
(c) Suppose
n
= 43 and
p
= 0.20. Can we approximate p̂ by a normal distribution? Why? (Use 2 decimal places.)
np = ???
nq = ???
(Yes/No) , p̂ (can/cannot) be approximated by a normal random variable because ____(np and nq do not exceed, nq exceeds, nq does not exceed, np does not exceed, nq does not exceed, np exceeds, both np and nq exceed) ________ (fill in blank)
What are the values of ?p̂
and ?p̂? (Use 3 decimal places.)
