The mean is 176     SD is given as 11.4

How many of 120 are 165# or more

176 - 165 = 11       11/11.4 = 965 standard deviations LESS than the mean....so - .1965 SD from the mean

Using NEGATIVE z-score table

   -.965 is approx .1673     in other words, 16.73 will weigh LESS than 165   ....the remainder    100% - 16.73% = 83.27% will weigh MORE

 

83.27% x 120 = 99.9 ~~ 100 players will weigh more than 165
