Explain what "98% confidence" means in a 98% confidence interval, What does "98% confidence" mean in a 98% confidence interval? O A. If 100 different confidence intervals are constructed, each based on a different sample of sizen from the same population, then we expect 98 of the intervals to include the parameter and 2 to not include the parameter. O B. The probability that the value of the parameter lies between the lower and upper bounds of the interval is 98%. The probability that it does not is 2%. O C. The confidence interval includes 98% of all possible values for the parameter. O D. The value of the parameter lies within 98% of a standard deviation of the estimate.
