Explain what we mean by a confidence level (exp. 95%) The percentage of intervals, based on all possible samples of the same size taken from the same population, that contain the parameter. For example, if we construct 100 95% confidence intervals using 100 samples of the same size, approximately 95 of the intervals will contain the true parameter and 5 will not. A point estimate is the value of a _________ that estimates the value of a ____________ statistic, parameter ...
