The Chevalier de Mere, a seventeenth century gambler, thought that it paid to bet evens on the event: A : you will get one or more sixes when four unbiased dice are thrown In other words, the Chevalier thought that P(A) > 1/2. (i) (a) Show that the probability of this event occurring is, in fact, 0.5177. (b) The experiment of throwing four unbiased dice is performed 10 times and results in the event A occurring 8 times. (1) Write down an equation which must be satisfied by pz, a lower 95% confidence limit for p = P(A) . (2) Verify that pz = 0.493 satisfies this equation. (3) Comment on this value of pz relative to the true value of p as specified in part (i)(a). [6] (ii) The experiment of throwing four unbiased dice is performed 1,000 times and results in the event A occurring Y times. (a) Write down a large sample expression for pz , a lower 95% confidence limit for p = P(A). (b) Determine how large Y would have to be for py to be greater than 1/2. (c) Using the true value of p as specified in part (i), calculate the probability that pz will, in fact, be greater than 1/2. [8] (iii) For the situation where the experiment is performed 10,000 times: (a) repeat part (ii)(b) (b) repeat part (ii)(c) and comment briefly on any difference between your two answers.

(ii) The following data and graduated rates of mortality (indicated by q, ) refer to a certain mortality investigation.

In a mortality investigation, the actual number of deaths at age a last birthday is d,. The goodness-to-fit between the data and the force mortality, A,+4, over the age range 21, mi +1, ... ,21 + m - 1 is often tested using the statistic ntm-1 (dx - EffIt;) C = > where Ef is the central exposed to risk corresponding to dr.
