10. Find the variance of the distribution.                   A certain make of car tyre can be safely used for 25 000km on average before it is replaced. The makers guarantee to pay compensation to anyone whose tyre does not last for 22 000km. They expect 7.5% of all tyres sold to qualify for compensation. Assuming that the distance X travelled before a tyre is replaced has a normal probability distribution. Use this information to answer questions 10-11. 11. Find the standard deviation of X.
