What is the \(z\)-score of \(x = 9\), if it is 1.5 standard deviations to the left of the mean? What is the \(z\)-score of \(x = 7\), if it is 0.133 standard deviations to the left of the mean? About what percent of the \(x\) values from a normal distribution lie within two standard deviations (left and right) of the mean of that distribution?
