What is the percentage of the population under the standard distribution curve between the Z scores of negative 1.96 and positive 1.96?
95% of the area falls between Z = -1.96 & 1.96.
What proportion of a normal distribution falls between z 1.16 and z 1.16?
0% of a normal (of any) distribution falls between z 1.16 and z 1.16. 1.16 - 1.16 = 0.
What exact percent falls the normal curve falls below at Z score of -2.00?
Although I cannot prove it, I doubt that there is a nice closed-form expression for this quantity; it's probably not a rational number. It's value is approximately 0.0227501319482. (Using Python code.)
What percentage of the data falls outside 2 standard deviation of the mean?
4.55% falls outside the mean at 2 standard deviation
What percentage is the second distribution sextile of a normal bell curve?
By definition, the 1st 6-tile is the point below which 1/6 of the population falls (irrespective of which distribution is involved). The 2nd 6-tile is the point below which 2/6 of the population falls. This is 100 * 1/3 ~ 33.3% of the population.
What is the area within the normal curve between -1SD and plus 1 SD?
The area within the normal curve between -1 standard deviation (SD) and +1 SD is approximately 68%. This means that about 68% of the data falls within one standard deviation of the mean in a normal distribution.
What area under the standard normal curve falls outside the z-value -2.5 and 2.5?
0.0124
What percentage of the area of a normal standard distribution falls between z and z?
Zero.
What percentage of the area of a normal standard distribution falls between z1 and z -1?
2
What is the percentage of the population under the standard distribution curve between the Z scores of negative 1.96 and positive 1.96?
95% of the area falls between Z = -1.96 & 1.96.
What percentage of the area of a normal standard distribution falls between z-1 and z -0.65?
-0.35
What proportion of the normal curve falls below a z score of 2.58?
Approx 0.995
What proportion of a normal distribution falls between z 1.16 and z 1.16?
0% of a normal (of any) distribution falls between z 1.16 and z 1.16. 1.16 - 1.16 = 0.

Why demand curve slopes downward?
Demand curve is slope downward because of inverse relationship between price and quantity.
Why is average revenue curve equal to the demand curve?
In normal demand curve, AR is equal to price and so it falls as output increases since the price has to be lowered in order to sell more products. based by: Jocelyn Blink, Ian Dorton, Economics Course companion, Oxford IB
What percent of data falls between 1 Standard deviation below and 2 stand deviations above the mean?
The answer will depend on what the distribution is. Non-statisticians often assum that the variable that they are interested in follows the Standard Normal distribution. This assumption must be justified. If that is the case then the answer is 81.9%
