A level 0.90 confidence interval is
A) any interval with margin of error ± 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 ± 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.

Answer:

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.
