How many standard deviations above the mean is the 90th percentile?
It is 1.28
How do you find the three sigma limits?
This is 3 standard deviations above and below the mean.
What would -2 standard deviation below the mean be?
It would mean that the result was 2 standard deviations above the mean. Depending on the distribution of the variable, it may be possible to attach a probability to this, or more extreme, observations.It would mean that the result was 2 standard deviations above the mean.

What is the benefit of knowing 3 standard deviations above and below the mean of data from a process?
If the process can be assumed to follow a Gaussian distribution then 99.7% of the outputs of the process will lie between those two limits. That may be of benefit in quality control if it is a production process.
If a very bright student is described as having an IQ that is three stand deviations above the mean what would the z-score be?
z = 3
A z-score of plus 1.6 represents?
It is 1.6 standard deviations above the mean.
How do you find two standard deviations above a mean?
It is mean + 2*standard deviation.
How many standard deviations above the mean is the 90th percentile?
It is 1.28
How do you find the three sigma limits?
This is 3 standard deviations above and below the mean.
If a data point has a corresponding score of -1.5 then it is one and a half standard deviations above the mean value.?
If you are talking about the z-value of a point on the normal curve, then no, it is 1.5 standard deviations BELOW the mean.
How good is an IQ of 155?
Toward the higher end of 3 standard deviations above average.
What percent lies more than 3 standard deviations above the mean?
15/1000
What is 2 Standard Deviations above an average of .1407?
The answer depends on the value of the standard deviation. Without that information, the question cannot be answered.

What percent of the data in a normal distribution lies more than 2 standard deviations above the mean?
2.275 %
What percent of the area of the normal curve is above and below 1.96 standard deviations ie. above 1.96 and below 1.96?
Above 1.96: 0.024998 = 2.5% below 1.96: 0.975002 = 97.5%
