Hiya guys/girls. I have a self study stats assignment to do which I have completed apart from one question where I have no idea what to do. Any help would be amazing.

" a batch of 800 components produced by a machine is expected to be normally distributed. A sample was taken and measured and found to have a mean of 15mm with a standard deviation of 0.02. Calculate how many of the batch will have a length:

a) between 15.00mm and 15.06mm

b) between 14.99mm and 15.05mm

c) greater than 15.04mm

d) less than 14.94mm"

once again thanks in advance for any help/advice/solutions

Shaun
