We have to find how many standard deviations is 14,500 away from the mean. This can be achieved by calculating the z-score
Z-score tells us how many standard deviations above or below is a sample value from the mean. A positive z value shows, sample value is above the mean.
z score can be calculated as = (Sample Value - Mean )/Standard Deviation) So, Z-score =
This means, 14,500 is 1.25 standard deviations above the mean value 12,000.
