The percentage of written test scores and interview scores are 40% and 60% respectively;

(3) The comprehensive score of the No.2 player is 92×0.4+88×0.6=89.6 (points),

The comprehensive score of player No.3 is 84×0.4+86×0.6=85.2 (points).

The comprehensive score of player No.4 is 90×0.4+90×0.6=90 (points).

The comprehensive score of player No.5 is 84×0.4+80×0.6=8 1.6 (points).
