Explain what "80% confidence" means in a 80% confidence interval. Question content area bottom Part 1 What does "80% confidence" mean in a 80% confidence interval? A. The confidence interval includes 80% of all possible values for the parameter. B. If 100 different confidence intervals are constructed, each based on a different sample of size n from the same population, then we expect 80 of the intervals to include the parameter and 20 to not include the parameter. C. The probability that the value of the parameter lies between the lower and upper bounds of the interval is 80%. The probability that it does not is 20%. D. The value of the parameter lies within 80% of a standard deviation of the estimate
