(b) Suppose n = 25 and p = 0.15. Can we safely approximate p by a normal distribution? Why or why not? --Select-- v, p ---Select-- v be approximated by a normal random variable because --Select--- (c) Suppose n = 43 and p = 0.20. Can we approximate p by a normal distribution? Why? (Use 2 decimal places.) np = nq = --Select--- P --Select-- v be approximated by a normal random variable because --Select-- What are the values of 4, and o,? (Use 3 decimal places.)
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
(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.)
