Think about the answer to part (d) regarding rounding. If a very small number of 18-certificate films were shown, what might the percentage be, and what would it round to?
Full Answer
The conclusion that *no* 18-certificate films were shown might be incorrect due to rounding. It is possible that a small number of 18-certificate films were shown, but they made up a very small percentage of the total. For example, if 1 out of 500 films was an 18-certificate, the percentage would be (1/500)*100 = 0.2%. If the percentages in the table were rounded to the nearest whole number, 0.2% would be rounded down to 0%. Therefore, a value of 0% in the table does not definitively mean the actual count was zero.
