Question

Background: In this DataLab, your task is to examine the sales data from a very large condominium development that consists of hundreds of units on and near a river. The RiverCondos files have a random sample of data from TWO different kinds of condos. One kind of condo has a river view (River_List Price, River_Sales Price, River_Days to Sell, and River_PMI) and the second kind does not have a river view (NoRiver_List Price, NoRiver_Sales Price, NoRiver_Days to Sell, and NoRiver_PMI). These variables describe the list price the last time a condo was put up for sale, the final sales prices, how many days it took the unit to sell, and whether or not the sale involved Principal Mortgage Insurance (PMI). List prices and sales prices are given in THOUSANDS of dollars. You begin by looking at your data to understand them better and to know what methods of inference you can safely use. When creating confidence intervals, which of the following variables will require you to check the np ≥ 10 and n(1-p) ≥ 10 conditions? (Check all that might apply...there may be more than one answer.) NoRiver_Days to Sell River_Days to Sell River_Sales Price NoRiver_Sales Price NoRiver_PMI River_List Price NoRiver_List Price River_PMI
