Question 925344
mean 12oz and a SD = 0.24oz.  {{{z = blue(x - 12)/blue(.24)}}} 
.......
Using the z-values to determine the Probability:
P(12.1488 < x < 12.1968) = P(.1488/.24 < z <  .1968/.24)
.......
 Using a TI calculator 0r similarly a Casio fx-115 ES plus
P(.1488/.24 < z <  .1968/.24) = normalcdf(.62, .82) = .0615
