Solution to question 1.1

This sampling procedure will not give a representative sample

The simple answer as to why it won't is that the sampling procedure is systematic rather than random.

We might go on to observe that the first five patients of each morning's surgery are unlikey to be representative of the patients as a whole. Particular types of patients will tend to come early in the morning others will prefer to attend later in the day. There is no guarantee that these different types of patients would have similar standards of dental hygiene.
