Performance metrics

Rocky Mountain BBQ is trying to become more efficient in training its chefs. It is experimenting with two training programs aimed at this objective. Both programs have basic and advanced training modules. The restaurant has provided the following data regarding the two programs after two weeks of implementation:

$\backslash$table$[[,\backslash$table$[[$Training$],[$Program A$]],\backslash$table$[[$Training$],[$Program A$]],\backslash$table$[[$Training$],[$Program A$]],\backslash$table$[[$Training$],[$Program A$]],\backslash$table$[[$Training$],[$Program A$]],\backslash$table$[[$Training$],[$Program B$]],\backslash$table$[[$Training$],[$Program B$]],\backslash$table$[[$Training$],[$Program B$]],\backslash$table$[[$Training$],[$Program B$]],\backslash$table$[[$Training$],[$Program B$]]],[$New chef #$,1,2,3,4,5,6,7,8,9,10],[$Hours of basic training,$21,25,27,21,21,22,23,27,29,22],[$Hours of advanced training,$10,5,9,12,9,6,5,0,2,4],[$Number of chef mistakes,$13,13,16,15,13,6,5,10,4,8]]$

a$.$ Compute the following performance metrics for each program:

$(1)$ Average hours of employee training per chef, rounded to one decimal place.

Program A: $$ hrs$.$ per chef

Program B: $$ hrs$.$ per chef

$(2)$ Average number of mistakes per chef, rounded to one decimal place.

Program A: $$ mistakes per chef

Program B: $$ mistakes per chef

b$.$ Which program should the restaurant implement moving forward?
