I am working on some statistics problems found in a introductory book on statistics, however i am having trouble with the following problem. It reads,
You are quoted some statistic, such as the number of imports into a country, a companys profits, or the number of seconds it took a sprinter to win a race. What is the chance that the first digit of the statistic is either a 1 or 2. Note any approximations and assumptions made.
The Attempt at a Solution
I know that for each statistic read it must begin with a digit between 1 through 9. Hence i can deduce a 2 in 9 chance that the digit is either a 1 or 2. This is far as i can get, any help would be much appreciated as my statistical knowledge is very limited.
