Suppose in a statistics class, 60% of the students are female. Suppose 15 students from the class are randomly selected. (i) Use the normal approximation to the binomial to calculate the probability that this randomly selected group will contain ether seven or eight female students. (ii) Use the binomial distribution to calculate the probability that this randomly selected group will contain either seven or eight female students and compare this result to the result in problem (i)

3. Consider a property market where the price of your apartment is mod- elled by a binomial random variable. Under current market conditions, the probability that the value of your apartment increases in value by 5% (of its original value) in one month is 0.45. The probability that it decreases in value by 5% (of its original value) in one month is 0.55. Given your past experience with lockdowns and apartment living, you decide to relocate to a regional area in 6 months time. Let X denote the number of increases in the price of your apartment over these 6 months. (a) Find E(X) and o(X). (b) Let Y be the random variable which models the percentage change in the price of your apartment. Then Y = 0.05.X-0.05(6-X) because 0.05.X is the total percentage increase in price and 0.05(6- X) is the total percentage decrease in price. Simplify the expres- sion for Y in terms of X. Then using (a), find E(Y) and o(Y).
3. Suppose that a fair coin (probability of heads equals 1/2) is tossed independently 10 times. Use the table of the binomial distribution given at the end of this book to find the probability that strictly more heads are obtained than tails.
In studies for a medication, 12 percent of patients gained weight as a side effect. Suppose 530 patients are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 64 patients will gain weight as a side effect. (b) no more than 64 patients will gain weight as a side effect. (c) at least 75 patients will gain weight as a side effect. What does this result suggest?

(a) Using It to test all of the wells in the area, the binomial distribution, what is the probability that exactly 3 wells have the impurity, assuming that the conjecture is correct? (b) What is the probability that more than 3 wells are impure?
In studies for a medication, 7 percent of patients gained weight as a side effect. Suppose 565 patients are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 40 patients will gain weight as a side effect. (b) no more than 40 patients will gain weight as a side effect. (c) at least 51 patients will gain weight as a side effect. What does this result suggest? (a) P(40) = (Round to four decimal places as needed) (b) P(X< 40) = (Round to four decimal places as needed) (c) P(X251) = (Round to four decimal places as needed) Since 51 is than 7% of the patients, this suggests that the proportion of patients that gain weight as a side effect is 0.07.
