STATT2 6.6.020. MY NOTES Suppose we have a binomial experiment in which success is defined to be a particular quality or attribute that interests us. (a) Suppose n = 45 and p = 0.23. Can we approximate p by a normal distribution? Why? (Use 2 decimal places.) np ng Yes p can be approximated by a normal random variable because |both np and nq exceed What are the values of u, and o ? (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? No p cannot be approximated by a normal random variable because np does not exceed (c) Suppose n = 43 and p = 0.15. Can we approximate p by a normal distribution? Why? (Use 2 decimal places.) np = ng = Yes v p can vv be approximated by a normal random variable because both np and nq exceed v What are the values of u and o ? (Use 3 decimal places.) Need Help? Read It
