It is not a valid sample because it is not a random sample of population. Participants who respond to a newspaper advertisement may not be representative of the entire population that the researcher is studying.

sample Adventure Beach. cruise Ski
A. 6. 5. 70. 19
B(. 1. 6. 72. 21
Which of the following inferences can be made based on the data
Most members prefer a beach vacation
Most members prefer an adventure vacation
More members prefer an adventure vacation and a ski vacation than a cruise vacation.
More members prefer a beach vacation and a ski vacation in an adventure vacation
None of the above inferences can be made based on the data.
The data only shows the preferred vacation types of two random samples of ten members of the travel club. It does not provide information about the preferences of the entire travel club population. Additionally, the data does not allow for direct comparisons between the two samples, as they have different proportions for each vacation type.
To make valid inferences about the travel club population, a larger and more representative sample would need to be used, and appropriate statistical tests would need to be conducted.
