(a) At an accident black spot junction, road accidents generally occur at a rate of 5 per month, on average. After road modifications, there is 1 accident in the first month. Does this provide evidence that the modifications have reduced the risk of accidents? (b) One member of the local district council examines the detailed records, and finds that in the two months immediately before the modifications there were 10 accidents. On the basis of this information alone, with the fact that there was 1 accident in the following month, would you conclude that there has been an improvement?
