Provide accurate answers to the following questions. Kindly explain them.

In an investigation into a patient's red corpuscle count, the number of such corpuscles appearing in each of 400 cells of a haemocytometer was counted. The results were as follows: No. of red blood 0 2 3 4 5 6 7 8 corpuscles No. of cells 40 66 93 94 62 25 14 5 1 It is thought that a Poisson distribution with mean / provides an appropriate model for this situation. (i) (a) Estimate /, the Poisson parameter. (b) Test the fit of the Poisson model. [8] (ii) For a healthy person, the mean count per cell is known to be equal to 3. For a patient with certain types of anaemia, the number of red blood corpuscles is known to be lower than this. Test whether this patient has one of these types of anaemia.

Even a conservative estimate of net present value shows that this is likely to be a successful investment. The directors have advised the engineer that they will not proceed with the project because it will be difficult to explain to the shareholders. The technology is simply too difficult to understand and there will be a five year development phase. Discuss the logic of the directors' position with respect to this project. [5] 16 Discuss the assertion that the cash flow statement is unnecessary because it is easy to see whether the closing bank balance is higher or lower than the opening bank balance. [5] 17 A famous accounting scandal involved a company's decision to recognise the premiums from the sale of holiday insurance contracts when the contracts were sold, rather than waiting until after the customer's safe return from holiday (which was the normal practice followed by other companies). There were no specific accounting standards to deal with this matter. Discuss the issues associated with recognising the profit from the sale of travel insurance in this way in terms of accounting concepts. [5]
