What does "90% confidence" mean in a 90% confidence interval?
a.) if 100 different confidence intervals are constructed, each based on a different sample size n from the same populateion, then we expect 90 of the intervals to include the parameter and 10 to not include the parameter.
b.) the value of the parameter lies within 90% of a standard deviation of the estimate.
c.) the confidence interval includes 90% of all possible values for the parameter.
d.) the probability that the value of the parameter lies between the lower and upper bounds of the interval is 90%. the probability that it does not is 10%.
