The correct answer is B. The sample size of five was too small. A sample size of only five is too small to accurately represent a larger population. The results may not be representative of the entire population and can be biased. Therefore, Ira's results cannot be considered valid.
That is true. I should of considered that. Thanks..
You're welcome! Sample size is an important factor to consider when conducting surveys or experiments. It's always a good idea to aim for a sample size that is large enough to provide accurate and representative results.
