Is it true or false that The area under a normal distribution curve is always positive even if the z value is negative?
It is true. Because the normal distribution is above the horizontal axis for all values, the area under it is a positive quantity no matter the z value.
What is z-chart in statistics?
A z-chart in statistics is a chart that contains the values that represent the areas under the standard normal curve for the values between 0 and the relative Z-score.
Do z-scores have a units of measure?
No, they do not. They are pure numbers.
What is true if someone has a z score of zero?
Z score of 0 is the mean of the distribution.
True or False the probability that a standard normal random variable Z is between 1.50 and 2.10 is the same as the probability Z is between -2.10 and -1.50.?
It is true because the distribution is symmetrical about Z=0.
What is one advantage of transforming X values into z-scores?
True or False, One major advantage of transforming X values into z-scores is that the z-scores always form a normal distribution
What is the translation of a point z to a two units to the right of z?
(z,z+2) or (z+2,z)
Truth table for 3-inputs OR gate?
It is not easy to illustrate this in a table since it would need to be a 3-d table. The browser which we are required to use is bad enough for ordinary tables. So here goes:X = True, Y = True, Z = True then (X or Y or Z) = TrueX = True, Y = True, Z = False then (X or Y or Z) = TrueX = True, Y = False, Z = True then (X or Y or Z) = TrueX = True, Y = False, Z = False then (X or Y or Z) = TrueX = True, Y = True, Z = True then (X or Y or Z) = TrueX = True, Y = True, Z = False then (X or Y or Z) = TrueX = True, Y = False, Z = True then (X or Y or Z) = TrueX = True, Y = False, Z = False then (X or Y or Z) = FalseThe simple way to remember is that the OR gate gives False only when each input is False.
Is it true or false that The area under a normal distribution curve is always positive even if the z value is negative?
It is true. Because the normal distribution is above the horizontal axis for all values, the area under it is a positive quantity no matter the z value.
Who sold the most Jay-Z or 50 cent?
50 Cent-(24.5 million units). Jay Z-(18.4 million units).
What is the ranges of z values corresponding to a probability of 0.8213?
-1.13 < z < 1.65
What is the values of vitamin A to Z?
There is vitamin A (but no vitamin Z .. just the mineral Zinc).
What is z-chart in statistics?
A z-chart in statistics is a chart that contains the values that represent the areas under the standard normal curve for the values between 0 and the relative Z-score.
What is the probability that a data value in a normal distribution is between a z-score of -0.28 and a z-score of 0.64?
-0.92
Who had more number 1 albums 50 cent or jay z?
50 Cent-(24.5 million units). Jay Z-(18.4 million units).
How can we assess differences in quality or performance by simply comparing z values under a standard normal curve?
z value looks at standard deviations away from the mean. if its tests scores, a higher positive z value means they are higher away from the mean in a positive direction the opposite is true for a negative z score.
Does the solution to a system of three equations in three variables is always one point?
No. There could be no solution - no values for x, y, and z so that the 3 equations are true.
