To explain: The study can be conducted in the state which can be representative of the latest government results.
An observational study with random sampling has to be performed so that the people who live in his state are representative of the government results.
Given:
To estimate the public feeling about the economy, a researcher conducts a study to verify if the people who live in his state are representative of the latest government results.
Concept used:
The random sampling method is where every subject has an equal chance of being selected without any bias and an observational study is where the researcher observes the data to analyse and does not have any control.
Explanation:
The researcher observes the people who live in his state to see if it is representative of the latest government results, thus it can be considered as an observational study and to eliminate any bias it would be better if random sampling is considered. Thus the researcher should conduct an observational study with random sampling to determine if the people who live in his state are representative of the latest government results.

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. Who is correct?arrow_forward
