A flooring company sells carpet by the metre off of a standard sized roll. The mean amount of carpet sold per month is known to have a normal distribution. If the probability of selling more than 1,000 metres per month is 0.0668 and the standard deviation is 100 metres, what is the mean amount of carpet sold? 900 1100 1150 850
