From a random sample of households, the number of television sets are listed. Find the sample mean and standard deviation of the data.
\n" ); document.write( "Number of televisions 0 1 2 3 4 5
\n" ); document.write( "Number of households 1 8 13 10 5 3
\n" ); document.write( "----------------------------------------
\n" ); document.write( "Multiply each # of tv's by its corresponding # of households = 99
\n" ); document.write( "Divide by the # of households to get the mean # of tv's = 2.475
\n" ); document.write( "----------
\n" ); document.write( "mean = 2.475
\n" ); document.write( "std = 1.2401
\n" ); document.write( "=================
\n" ); document.write( "I used a TI-84 to get the std.
\n" ); document.write( "Enter data into L1,L2
\n" ); document.write( "Select STAT; CALC; 1-Var Stats L1,L2 ; ENTER
