(b) Suppose n = 25 and p = 0.15. Can we safely approximate p by a normal distribution? Why or why not? --Select-- v, 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 = = bu Select-- Select--- be approximated by a normal random variable because --Select-- same choices as other fill in blank What are the values of u, 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 exceeds, np and nq do not exceed, nq exceeds, nq does not exceed, both np and nq exceed, np does not 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.)
(Yes, no) p̂ (can, cannot) be approximated by a normal random variable because (np exceeds, np and nq do not exceed, nq exceeds, nq does not exceed, both np and nq exceed, np does not exceed) ___________ (fill in blank).
