Statistics help? X is distributed normally, P(x>=59.1) =0.0218 and P(x>=29.2)=0.9345 Find the mean and standard deviation of the distribution, correct to 3 significant figures.
If you are expected to do this kind of problem then you should know that, given a normal distribution with mean and standard deviation , variable x corresponds to a "standard normal distribution" . Here, you need to look up, in a table of the standard normal distribution, corresponding to and such that . Then, using those values for and , solve the two equations and for and .
