What is the formula for the standard error of the normal approximation to the p distribution? ^ij= What is the mean of the p^ distribution? p^=pose we have a binemial experiment in which success is defined to be a particular quality or attribute that iaterests use (a) Suppose n a 45 and p=0.16. Can we approximate p by a normal distribution? Waty? (Use 2 decimal places,) np= be approximated by a nomal randern variable bocause What are the values of and of ? (use 3 dedmal piaces.). i=gpi= (b) Suppose n=25 and p=0.15. Can we safely approxintate p by a normal dietribution? why or why not? P. p p q be approximated by a nermal random variable because (c) Suppose n. 44 and p=0,33. Can we approximate p ty a notmu distribution? Why? (Use 2 decimal places.) n=n4= What are the values of yy and a 2 (Uee I dedimal places.) ii=.
