Which of the following expenses would not appear on a selling and administrative expense budget? Depreciation Indirect labor Property taxes Sales commissions 3. Consider a population P= \{people considering treatment of hand warts\}. Let X= Treatment (Duct Tape or Freezing) and Y= Removed (Yes=warts removed, Noswarts not removed). Consider the following two studies... Study 1. s+SRS(n=200,P). After 2 months, record (X,Y):s; see count summary in Table 1. Study 2. s+ Available_Case_Sample (n=200,P). Randomly assign 100 of units in sample s to (X= Duct Tape ) treatment and 100 to (X= Freezing ) treatment. After 2 months, record Y : s values. The (X,Y):s count summary is in Table 2. 3(a). True or False. Study 1 is an Observational Study and Study 2 is a Randomized Designed Experiment. B. False 3(b). Which study is more appropriate for addressing the causal claim that "Freezing is better than Duct Tape for the treatment of warts"? Explain your answer. 3(c). True or False: Because Study 2 is based on a non-probability (aka haphazard sample), a causal effect of Treatment (Duct Tape vs. Freezing) cannot be measured. A. True B. False 3(d). Compute the Relative Risk props(Y=YesX=Freezing)props(Y=YesX=DuctTape) values for both studies, Study 1 and Study2. Show your work
