A university has 27 academic units ranging in size from 2 to 92 faculty members. A sample of 10 academic units were selected with probabilities proportional to size and with replacement, and within each sample academic unit an SRS of four (or fewer, if Mi < 4) members were selected. Note that academic unit 14 appears three times in the sample; each time it appears, a different subsample was collected. Find the estimated total number of publications, along with its standard error. Also, and its 95% confidence interval.
