Suppose we have a binomial experiment in which success is defined to be a particular quality or attribute that interests us. (a) Suppose n = 39 and p = 0.32. Can we approximate p by a normal distribution? Why? (Use 2 decimal places.) np = ng = -Select- p --Select- | be approximated by a normal random variable because -Select- What are the values of u; and o ? (Use 3 decimal places.) HA= p (b) Suppose n = 25 and p = 0.15. Can we safely approximate p by a normal distribution? Why or why not? -Select--, p --Select-|be approximated by a normal random variable because --Select- (c) Suppose n = 47 and p = 0.39. Can we approximate p by a normal distribution? Why? (Use 2 decimal places.) np = ng = -Select- v , p -Select-- | be approximated by a normal random variable because -Select-- What are the values of u; and o;? (Use 3 decimal places.)
