10.) The television picture tubes of manufacturer Sumsun have a mean lifetime of 7 years and a standard deviation of 0.8 year, while those of manufacturer Fillip have a mean lifetime of 6.0 years and a standard deviation of 0.7 year. A random sample of 64 tubes is taken from manufacturer Sumsun while a random sample of 49 tubes is taken from manufacturer Fillip. What is the probability that the difference between the mean lifetimes of the television picture tubes from the two manufacturers is not more than 0.8 year?
