IQ test scores are normally distributed with a mean of 97 and a standard deviation of 11.An individual's IQ score is found to be 123.Find the zscore corresponding to this value

Z = (scoremean)/SD

For a particular value, this table gives the percent of scores between the mean and the zvalue of a normally distributed random variable. What percent of the total population is found between the mean and the zscore, assume z = 2.79
