The answer depends on the value of the new point. If the new value is near the mean then the new standard deviation (SD) will be smaller, if it is far away, the new SD will be larger.

A score set has a mean of 53 and a standard deviation of 5.6 If each score was multiplied by 0.9 and then had 7 added state the new standard deviation?
Standard deviation is the spread of the data. If each score has 7 added, this would not affect the spread of the data - it would be just as evenly spaced or clumped up, but 7 greater. The only thing that would affect the spread is multiplying every data point by 0.9. This makes distances between the data points 0.9 times as big, and thus makes the standard deviation 0.9 times as big. The standard deviation was 5.6, and so now is 5.6x0.9 = 5.04

How do you make decimals into standard form?
Move the decimal point to the left or right so that it is after the first non-zero digit. Count the number of places that the decimal point has been moved.The mantissa for the standard for is the new decimal representation. The index, for the 10 is the number of places that the decimal point was moved: positive if the dp was moved to the left and negative if to the right.So, for example,34500 = 3.45*10^40.000345 = 3.45*10^-4

Does adding stocks decrease a portfolios standard deviation and risk?
It depends on the standard deviation and risk of the new stock.
The standard deviation of a distribution is 5 if you mutiply each score by 3 what would the new standard deviation be?
It would be 3*5 = 15.

A large set of data has a mean of 100 and standard deviation of 15Five are addedto each score in data what is the new mean and standard deviation?
The mean will move up by 5 also as the whole data set has shifted up by 5, hence the mean is 105. The spread of the data has not changed, its just been "lifted up and moved along 5" and so the standard deviation is the same, i.e. 15 Hope this helps
How is it possible to convert normal distributions to the standard normal distribution?
use this link http://www.ltcconline.net/greenl/Courses/201/probdist/zScore.htm Say you start with 1000 observations from a standard normal distribution. Then the mean is 0 and the standard deviation is 1, ignoring sample error. If you multiply every observation by Beta and add Alpha, then the new results will have a mean of Alpha and a standard deviation of Beta. Or, do the reverse. Start with a normal distribution with mean Alpha and standard deviation Beta. Subtract Alpha from all observations and divide by Beta and you wind up with the standard normal distribution.

What does Relative standard deviation tells us?
Relative Standard Deviation (RSD) is a measure of precision (not accuracy). RSD is sometimes called coefficient of variation (CV) and often is calculated as a percentage. s = standard deviation x = mean RSD = s/x, as a percentage, (s/x) *100 The RSD allows standard deviations of different measurements to be compared more meaningfully. For example, if one is measuring the concentration of two compounds A and B and the result is 0.5 (+/-) 0.4 ng/mL for compound A and 10 (+/-) 2 ng/mL for compound B, one may look at the standard deviation for compound A and say because it is lower (0.4 vs. 2) than for B, the measurement for A was more precise. Actually this is not the case. When the %RSD is used the new values for compound A and B are 0.5 (+/-) 80% and 10 (+/-) 20% respectively, therefore, the measurement for compound B is more precise.
What is standarizing variable?
An ordinary variable is standardised by taking a linear transformation of it such that the new variable has standard properties. For example, if X is a Gaussian (Normal) variable with mean mu and standard deviation sigma, then Z = (X - mu)/sigma has a Normal distribution with mean 0 and SD = 1: it has been standardised.
What do you do to balance the line when the duration of the jobs is probablistic?
First, we assume all the probabilities follow normal distribution, so the sum of two means also follows the normal distribution and the standard deviation is the sum of the standard deviations.The method goes as follows:Since you have the cycle time for each workstation, assign a value that should be the limit between the duration of the jobs and the cycle time,begin firstly by standardizing the first job which has to be assigned, with the mean of this job and its standard deviation. If it does not exceed the cycle time, assign this job in this station.add to the current workstation the second job and add the two means together as well as the standard deviations. If the cycle time is exceeded, open a new workstation.
