In studies for a medication, 15 percent of patients gained weight as a side effect. Suppose 693 patients are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 104 patients will gain weight as a side effect. (b) no more than 104 patients will gain weight as a side effect. (c) at least 118 patents will gain weight as a side effect. What does this result suggest? (a) P(104) 2 (Round to four decimal places as needed) (b) P(X S 104) = (Round to four decimal places as needed) (c) P(X2118)= (Round to four decimal places as needed) Since 118 is V than 15% of the patients. this suggests that the proportion of patients that gain weight as a side effect is V 0.15. n...... . --'r - The number of chocoiate chips in an 18ounce bag of chocolate chip cookies is approximately normally distributed with a mean of 1252 chips and standard deviation 129 chips. (3) What is the probabiiity that a randomly selected bag contains between 1100 and 1500 chocolate chips, inclusive? (b) What is the probability that a randomly selected bag contains fewer than 1000 chocolate chips? (c) What proportion of bags contains more than 1225 chocolate chips? (d) What is the percentile rank of a bag that contains 1000 chocolate chips? (a) The probability that a randomly selected bag contains between 1100 and 1500 chocolate chips, inclusive, is (Round to four decimal places as needed.) (b) The probability that a randomly selected bag contains fewer than 1000 chocolate chips is (Round to four decimal places as needed.) (c) The proportion of bags that contains more than 1225 chocolate chips is (Round to tour decrmal places as needed ) (d) A bag that contains 1000 chocolate chips is in the rd percentile. (Round to the nearest integer as needed.)
