Final answer:
The sample of flowers in Patrick's neighborhood is likely to be biased because each block has an equal number of flowers, suggesting a selection bias.
Step-by-step explanation:
The sample of flowers in Patrick's neighborhood is likely to be biased. Since each block has an equal number of flowers, this suggests that the observer intentionally selected blocks with the same number of flowers.
An unbiased sample would entail the observer randomly selecting blocks with different numbers of flowers, which would provide a more representative picture of the entire neighborhood.
Thus, the sample of flowers in Patrick's neighborhood is likely to be biased.
