document.write( "Question 1122319: At General Hospital, nurses are given performance evaluations to determine eligibility for merit pay raises. The supervisor rates the nurses on a scale of 1 to 10 (10 being the highest rating) for several activities: promptness, record keeping, appearance, and bedside manner with patients. Then an average is determined by giving a weight of 2 for promptness, 4 for record keeping, 1 for appearance, and 3 for bedside manner with patients. What is the average rating for a nurse with ratings of 2 for promptness, 7 for record keeping, 2 for appearance, and 3 for bedside manner? (Enter your answer to one decimal place.) \n" ); document.write( "

the average for frequency data is calculated as follows:\r

document.write( "
\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you multiply the rating by the weight to get the weight * rating.\r

\n" ); document.write( "\n" ); document.write( "you then divide the sum of the weight * rating scores by the sum of the weight scores to get the average.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the sum of the weight * rating scores was 43.
\n" ); document.write( "the sum of the weight scores was 10.
