Question 280798
The length of wooden chopsticks produced by a machine is normally distributed with a standard deviation of 0.5 cm / 5 mm. It is found that 1% of all these chopsticks are less than 24 cm long. Find the mean length of the chopsticks produced by the machine.

What do you mean by "std of 0.5 cm/5 mm"????
