Document Summary
February 7 2014: the colour of the rst page of this examination booklet (the cover sheet) is: (a) white ** (b) yellow, suppose we draw a simple random sample of four observations, and nd that the values are: What is the standard deviation of these values? s = 7. 274384. They set several cage traps in the area and capture 15 wild rabbits. The 15 rabbits are weighed and they are found to have a mean weight of 3. 6 kg. Suppose that, in reality, the average weight of all wild rabbits in the area is 4. 2 kg. This question is very similar to question 12 of the gathering data exercises. Consider the following statements: 3. 6 is the value of a statistic. True, since it is a value based on sample data. True, since it is the true value for the entire population. The 15 rabbits are a strati ed random sample from the population of interest.
