Investigation:

To examine how the age of a second hand car affects its price. Also to check if there is any relationship with the age and price drop.

Hypothesis:

Although naturally there will be some exceptions I believe that in most cases, as the age increases, the price of a 2nd hand car will decrease. This is clearly shown if you divide the old price by the price when new.

Method:

I have created a frequency table to firstly sort out my sample size. I will divide the frequencies by 5 to give me a final sample size of 20 from the original sample of 100. I will divide each individual frequency by 5 to determine how many of each age is needed for a fair sample.

This is the Frequency table of the sample size of 100.
