Approximately 0.15% of the data lies to the left of (μ-3σ) and 0.15% of the data lies to the right of (μ-3σ). Answers: What percentage of the area under the normal curve lies as given below?

What is the percentage of the area under the normal curve lies?

In general, about 68% of the area under a normal distribution curve lies within one standard deviation of the mean. That is, if ˉx is the mean and σ is the standard deviation of the distribution, then 68% of the values fall in the range between (ˉx−σ) and (ˉx+σ) .

What percentage of the area under the normal curve lies between μ − σ and μ 2σ?

About 68% of the x values lie between the range between µ – σ and µ + σ (within one standard deviation of the mean). About 95% of the x values lie between the range between µ – 2σ and µ + 2σ (within two standard deviations of the mean).

How do you determine the area under the standard normal curve that lies to the right?

To find the area to the right of a positive​ z-score, begin by reading off the area in the standard normal distribution table. Since the total area under the bell curve is 1, we subtract the area from the table from 1. For example, the area to the left of z = 1.02 is given in the table as . 846.Jan 20, 2019

How do you determine the area under the standard normal curve that lies to the left?

0:133:46Finding the Area Under a Standard Normal Curve Using the TI-84YouTubeStart of suggested clipEnd of suggested clipOkay so in the first example we want to find the area under. This standard normal curve. That is toMoreOkay so in the first example we want to find the area under. This standard normal curve.

What percentage of the area under the normal curve is to the left of the following z-score?

The corresponding area is 0.8621 which translates into 86.21% of the standard normal distribution being below (or to the left) of the z-score.May 30, 2019

What percent of the area under the normal curve lies within 0.5 standard deviations from the mean?

Reading from the chart, it can be seen that approximately 19.1% of normally distributed data is located between the mean (the peak) and 0.5 standard deviations to the right (or left) of the mean. This chart shows only percentages that correspond to subdivisions up to one-half of one standard deviation.

What percent of the area under a normal curve is within 1 standard deviations?

68%For the standard normal distribution, 68% of the observations lie within 1 standard deviation of the mean; 95% lie within two standard deviation of the mean; and 99.9% lie within 3 standard deviations of the mean.Jul 24, 2016

What percent of the area under a normal curve is within 3 standard deviation?

99.7%The Empirical Rule states that 99.7% of data observed following a normal distribution lies within 3 standard deviations of the mean. Under this rule, 68% of the data falls within one standard deviation, 95% percent within two standard deviations, and 99.7% within three standard deviations from the mean.

What percent of the area under a normal curve is within 2 standard deviations?

Regardless of what a normal distribution looks like or how big or small the standard deviation is, approximately 68 percent of the observations (or 68 percent of the area under the curve) will always fall within two standard deviations (one above and one below) of the mean.Apr 12, 2021

How many percent of a score is between Z 0 and Z 1?

Because z-scores are in units of standard deviations, this means that 68% of scores fall between z = -1.0 and z = 1.0 and so on. We call this 68% (or any percentage we have based on our z-scores) the proportion of the area under the curve.May 1, 2021
