Suppose that 30% of all homes purchased in 2018 were considered investment properties. If a sample of 1000 homes sold in 2018 is obtained: a) Describe the 3 main components of the distribution of sample proportions (the mean, the standard deviation and the shape). b) Would it be unusual if more than 320 homes were purchased as investment properties? Hint: you need to find p-hat first.

Which of the following statements are true? (select all that apply.) a quasi-static process is one in which the system is never far from being in equilibrium. when a system can go from state 1 to state 2 by several different processes, the amount of heat absorbed by the system will be the same for all processes. the internal energy of a given amount of an ideal gas depends only on its absolute temperature. when a system can go from state 1 to state 2 by several different processes, the work done on the system will be the same for all processes. when a system can go from state 1 to state 2 by several different processes, the change in the internal energy of the system will be the same for all processes. for any substance that expands when heated, its cp is greater than its cv.
