To explain: The study method used in a given situation and if the sample statistics can estimate the population parameter with no bias.
A survey is conducted to know about the time spend on household chores each week by students. As the sampling method used is simple random sampling the sample statistics can be used to estimate the population parameter without any bias.
Given:
A list of students are randomly selected from the school data base and was questioned about the time they spend on household chores each week.
Concept used:
The random sampling method is where all objects of the sample are equally likely to be selected in the sample.
Interpretation:
The sample was created by randomly selecting the students from the school database. Each selected student was asked a question about how much time they spent on household chores each week. Thus the study method is a survey and the sampling method is simple random sampling. The sample was selected randomly selecting students from the school database, thus each student has an equal chance to be selected in the sample. Thus there exists no bias and sample statistics can be used to estimate the population parameter and the results can be generalised with respect to population.

They are playing a game where they randomly pick a card out of the hat four times, with replacement. Amy thinks that the probability of getting exactly two aces in four picks is equal to the probability of not getting exactly two aces in four picks. Samiha disagrees. She thinks that the probability of not getting exactly two aces is greater. The sample space of possible outcomes is listed below. A represents an ace, and K represents a king.
