Answer Happy

Suppose we have a binomial experiment in which success is defined to be a particular quality or attribute that interests us. (a) Suppose n = 30 and p = 0.25. Can we approximate p by a normal distribution? Why? (Use 2 decimal places.) op = nq - Yes both np and nq exceed can What are the values of , and ? (Use 3 decimal places.) (b) Suppose n = 25 and p = 0.15. Can we safely approximate p by a normal distribution? Why or why not? be approximated by a normal random variable because No Pcannot np does not exceed ng 44.5 be approximated by a normal random variable because (c) Suppose n = 50 and p = 0.11. Can we approximate p by a normal distribution? Why? (Use 2 decimal places.) np=5.5 Yes both np and nq exceed p can be approximated by a normal random variable because What are the values of , and o? (Use 3 decimal places.) 5.5 -2.2125
