What else can I help you with?
What area under the standard normal curve falls outside the z-value -2.5 and 2.5?
0.0124
Is the standard normal curve non symmetrical?
The standard normal curve is symmetrical.
What is the area under the standard normal curve?
the standard normal curve 2
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.
He area under the standard normal curve is?
The area under the standard normal curve is 1.
What area under the standard normal curve falls between the z value -1.5 and 2.5?
The area is 0.9270, approx.
How calibration curve is obtained using flame spectrophotometer?
A calibration curve for a flame spectrophotometer is obtained by measuring the absorbance of a series of standard solutions with known concentrations of the analyte. The instrument records the absorbance values at specific wavelengths. By plotting the absorbance against the concentration of the standard solutions, a linear calibration curve is achieved. This curve can then be used to determine the concentration of an unknown sample based on its absorbance value.
What are the properties of a standard normal curve?
It is a normal curve with mean = 0 and variance = 1.
What is the mean and standard deviation for the standard normal curve?
Mean = 0 Standard Deviation = 1
How do you prepare the standard curve?
To prepare the standard curve you will need linear graph paper, semi-log graph paper and absorbance. You can define your standard curve by finding the absorption or percent plot on the Y axis.
What is a value curve analysis?
Value curves are relatively simple but a powerful tool. A value curve analysis tells a company that what customers value and how they can meet the customer's need and competition.
What is the purpose of making a standard curve?
The values of many curves cannot be calculated analytically: the process requires painstaking numerical estimation. The values of a standard curve can be calculated once and published for ready reference. This means that, given any other curve in the same family, it is possible to transform it to the standard curve and the reference values can be used.
