A level 0.90 confidence interval is

A) any interval with margin of error Â± 0.90.

B) an interval computed from sample data by a method that has probability 0.90 of

producing an interval containing the true value of the parameter of interest.

C) an interval with margin of error Â± 0.90, which is also correct 90% of the time.

D) an interval computed from sample data by a method that guarantees that the probability

the interval computed contains the parameter of interest is 0.90.

Pablo Espinoza · Answer 1

Option B is correct.

Step-by-step explanation:

Confidence interval is the range of the values that the particular probability whose value will lie in the interval.

So, if a level is 0.90 confidence interval it means the value of the probability will lie in the given level.

Therefore, Option B is correct that is an interval computed from sample data by a method that has probability 0.90 of producing an interval containing the true value of parameter of interest.
