Question: 4. Consider the measuring device X = 17, 18, or 19, so that =1/+ 18+19 3 -=18 Find = the population standard deviation by filling

4. Consider the measuring device X = 17, 18, or 19, so that =1/+ 18+19 3 -=18 Find = the population standard deviation by filling out the following table: X X - H ( X - U)2 17 18 19 SSX 0=1 SSX 3 = ? Now take two measurements with this measuring device and find SD( 4 ) by filling out this next table: X1 X2 X X - H (X - 12 17 17 17 17 18 171/2 17 19 18 18 17 171/2 18 18 18 18 19 181/2 19 17 18 19 18 181/2 19 19 19 SS X SD ( X= SS X 9 = ? Statistical theory says that SD X = Vn v2 here. Compute 0/ V2 and check that this is equal to your calculation of SD(X)
