The weights of bags of rice are normally distributed with mean 2.04 kg and standard deviation σ kg. In a random sample of 8000 such bags, 253 weighed over 2.1 kg. Find the value of σ. I have done P(x>2.1)=253/8000 and P(x<2.1)=0.968375 But I'm not sure what to do next. Any help would be appreciated!
