Give three properties of a normal distribution function?
1.it is bell shaped.2.m.d=0.7979 of s.d 3.total area under the normal curve is equal to 1.
What is Frequency normal curve?
A frequency normal curve, often referred to as a bell curve, represents the distribution of data points in a dataset where most values cluster around the mean, creating a symmetrical shape. It illustrates the concept of normal distribution, where approximately 68% of the data falls within one standard deviation of the mean, 95% within two, and 99.7% within three. This curve is crucial in statistics as it helps in understanding probabilities and making inferences about population parameters based on sample data.
What are three characteristics of a normal curve?
A normal curve, or Gaussian distribution, is symmetric and bell-shaped, indicating that the data is evenly distributed around the mean. It has a mean, median, and mode that are all equal and located at the center of the curve. Additionally, approximately 68% of the data falls within one standard deviation of the mean, about 95% within two standard deviations, and around 99.7% within three standard deviations, known as the empirical rule.
How do the width and height of a normal distribution curve?
By standard practice, the normal distribution curve should be normalized so that the area under the curve is 1. This results in a height, at the mean, of about 0.4, i.e. the probability of a sample value being equal to the mean is 40 percent. The width of the normal distribution curve is infinite, as the tails are asymptotic to the X axis. It is easier to understand that the +/- one sigma area is 68.2 percent, the +/- two sigma area is 95.4 percent, and the +/- three sigma area is 99.6 percent.
What is a binormal?
A binormal is a line which is at right angles to both the normal and the tangent of a point on a curve, and, together with them, forms three cartesian axes.
What are the three characteristics of a supply curve?
The three characteristics of a supply curve are the slope, shift, and the curve's position. Together they help determine supply and demand trends.
What is one of the values of a variable which divides the distribution of the variables into three groups having equal frequencies?
A tertile or tercile.
How can a company have a downward demand curve but still have marginal revenue equal price?
If the Demand Curve is separate from the MR=P curve, the company can not be of Perfect Competition. It can exist in any other market structure: Monopolistic Competition, Monopoly, or Imperfect Competition. In each of these three structures, the Demand Curve will always fall twice as fast as the MP=P=AR Curve. To answer your question in these terms, the company can have a downward sloping Demand Curve separate from the MR=P curve if it is not in the PC Market Structure.
What is the abnormal range in albumin?
Prealbumin expected normal values are between 18 to 36 mg/dL (180 to 360 mg/L). These values will change from laboratory to laboratory due to different techniques and instrumentation used but results will be close to above mentioned values.
What are three parts of a formula?
Three parts of a formula include the equal sign to start the equation, cell references or values used in the calculation, and mathematical operators (+, -, *, /) to perform the calculation.

How do you graph the rational function y equals 3 over x?
This graph looks very similar to the famous equation of y equal 1 over x; in either case you get a curve which asymtotically approaches infinity at the y axis where x=0, and which asymptotically approaches zero as x approaches infinity. The difference is that if it is 3 over x, all the values will be three times higher than if it is 1 over x. But the shape of the curve is the same.
