I would use

#+TBLFM: $8 = vlen($3..$7) :: @>$2 = vmean($3..$7); E %.2f ::
@>$3..@>$7 = vlen(@address@hidden) :: @>$8 = vmean(@address@hidden); E %.2f

or

#+TBLFM: $8 = vlen($3..$7) :: @>$2 = vmean($3..$7) +.0; E f-2 ::
@>$3..@>$7 = vlen(@address@hidden) :: @>$8 = vmean(@address@hidden) +.0; E f-2

For +.0 and f-2 see
