Sample text

Of adult men in the age from 20 to 30, it is 162 centimetres. 4R we obtain 170 cent imetres, We are now to test the hypothesis that. e. just a natural spread, since 41 Likelihood Ratio the mean height is a random variable. Our null hypothesis will be that the mean height in the 1943-1948 age group is the same as in the 19081913 age group, the alternative hypothesis being that the mean height has increased over these 35 years. What follows is an illustration of the reasoning used in such situations.

Later in the book we will look at the risk in more detail, but at the point it is worth noting that the permissible risk level is an extremely subjective thing. You will have played cards or some gamble and will know that the gambler's behaviour is dramatically dependent on the amount of possible win or loss and on the character of the game, its heat. And in problems concerned with engineering and nature the estimates of the permissible risk appear to be also dependent on a variety of other factors, suchas prestige or qualification.

No use trying to explain to her that the only way of achieving this probability is to stay at home for ever. It is thus unclear what principles we are to be guided with in selecting the permissible probability of the first-type error for accidents. And what principles should be used by local authorities in setting speed limits. Pedestrians may think that if, say, the limit is increased from 50 to 60 kilometres per hour, this will make accidents more likel y. I n practice, this is not necessarily so, since higher speed limits are as a rule accompanied by improvements in traffic control, population education, higher penalties, and so on.
