e file P02_35.xisx contains data from a survey of 500 randomly selected households. Suppose you decide to generate a systematic random sample of size 25 from this population of data. How many such samples are there? What is the mean of Debt for each of the first three such samples, using the data in the order given? Round your answers to one decimal place, if necessary. Mean Sample 1 25 Sample 2 25 Sample 3 25 b. If you wanted to estimate the (supposedly unknown) population mean of Debt from a systematic random sample as in part a, why might it be a good idea to sort first on Debt? By sorting on Debt, we're sure that each systematic sample gets most of the smallest values, all v of the medium values, and most v of the largest values. If you do so, what is the mean of Debt for each of the first three such samples? Round your answers to one decimal place, if necessary. Mean Sample 1 25 Sample 2 25 Sample 3 25
