2.
According to Mia, what is a prior?
A belief held before seeing data
A way to calculate the exact answer
A type of rare event
A new piece of information gathered later
Explanation:
Mia says, ‘A prior is what we believe before data.’
3.

B Because rare events always happen in the same way
A Because rare events have little data available
D Because it only works with large datasets
C Because it eliminates the need for beliefs
Explanation:
Mia explains that Bayesian analysis is useful for rare events because ‘rare events have little data available.’
4.
What can be inferred about Bayesian analysis from Mia’s explanation?
D It works only when there is a lot of data
B It ignores prior knowledge and uses only new data
C It can predict rare events with absolute certainty
A It combines earlier beliefs with newer information to improve estimates
Explanation:
Mia says Bayesian analysis uses prior knowledge and new data to update beliefs, so it combines earlier beliefs with newer information.
5.
Why does Mia mention that rare events have little data available?
C To argue that prior knowledge is unnecessary
B To show that rare events should never be studied
A To explain why Bayesian analysis is especially helpful in that situation
D To prove that new data cannot change beliefs
Explanation:
Mia directly uses the lack of data for rare events to explain why Bayesian analysis is useful there.
