Using a standard normal distribution table, the area to the left of z = 1.95 is 0.974. This represents the probability that a randomly selected observation from a normally distributed population falls below a value of 1.95 standard deviations above the mean. The area to the left of z=1.95 can be found using a standard normal distribution table or calculator. Using a standard normal distribution table, we find the area to be 0.974.
