Final answer:
Isaiah's question is statistical because the number of visitors to an amusement park can vary; therefore, the data is not constant. Sample statistics may not accurately reflect population parameters if the sample is not representative.
Step-by-step explanation:
Isaiah is statistical because the data collected to answer it could vary. This variance is expected as the number of visitors to an amusement park can fluctuate due to various factors such as weather, holidays, or special events on particular days. Furthermore, if we consider the additional information regarding a survey conducted by Intel Corporation at a Smithsonian Institute's road show.
This asks us to reflect on whether all demographic and ethnic groups were equally represented at the event. Due to the specific location and nature of the event, it's plausible that the survey sample might not have perfectly mirrored the broader population demographic. Consequently, sample statistics may not accurately reflect the population parameters.
As for the study done to determine certain factors about the residents using a local park in San Jose, selecting the first house randomly and then every eighth house could be classified as a systematic sampling method. This method can be effective, but also holds potential for bias if there's a pattern in the population that coincides with the sampling pattern.
