What is the probability of randomly selecting values more then 2.57 standard deviations away from the mean in either a positive or negative direction in a normal distribution?
1% total 0.5% in either direction
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
Which is the first quadrant in a coordinate grid?
The top right one... it is the first because it is where both the x-value and y-values are positive. The second quadrant is the top left. The x-values are negative and the y-values are postive. The third quadrant is the bottom left. The x-values are negative and the y-values are negative. The fourth quadrant is the bottom right. The x-values are positive and the y-values are negative.
What does data distribution mean?
It is the set of values that a variable can take together with the probability or frequency distribution for those values.
The slope of line which has decreasing y values for increasing x is?
... negative.... negative.... negative.... negative.
What are beta values?
The probability that a statistical that will give give a false negative error.
What are not a possible value for a probability?
Negative values, values greater than 1, complex values.
Is negative 49 a probability?
No, it's not a probability since it's not set in terms of ratio of two values, such that the second value is greater than the first. For instance: 1 to 2 or 1 / 2. Also, probability is never negative.
Are the probability values always greater than or equal to 0 or less than or equal to 1 or all positive numbers?
Probability values are never negative and are always between 0-1 according to the definition Probability of A= Number of outcomes classified as A/Total number of possible outcomes
Can -0.51 be a probability?
No. The probability cannot be negative.
Can Probabilities take on negative values only when the events are occurring less than 50 percent of the time?
Probabilities can never be negative. A probability distribution is defined as follows:Every event has a probability of occurring between 0 and 1, inclusive.The sum of the probabilities of each event occurring is 1.
Does a negative z score yield a negative probability value?
no, z score can be negative but a probability is a always positive between 0 and 1.
Can probability be negative?
No, it can't.
How do the highest and lowest possible values for the variable compare in their probability of occurring to the values in the middle of the distribution?
The answer will depend on the skewness of the distribution.The Poisson distribution is defined for non-negative integers: 0, 1, 2, 3, 4 etc. So the lowest value is 0.For a Poisson distribution with parameter l=1 (when it is very skew), the probability of the lowest two values, 0 and 1, is 0.368 each and the probability tails off rapidly for higher values.The answer will depend on the skewness of the distribution.The Poisson distribution is defined for non-negative integers: 0, 1, 2, 3, 4 etc. So the lowest value is 0.For a Poisson distribution with parameter l=1 (when it is very skew), the probability of the lowest two values, 0 and 1, is 0.368 each and the probability tails off rapidly for higher values.The answer will depend on the skewness of the distribution.The Poisson distribution is defined for non-negative integers: 0, 1, 2, 3, 4 etc. So the lowest value is 0.For a Poisson distribution with parameter l=1 (when it is very skew), the probability of the lowest two values, 0 and 1, is 0.368 each and the probability tails off rapidly for higher values.The answer will depend on the skewness of the distribution.The Poisson distribution is defined for non-negative integers: 0, 1, 2, 3, 4 etc. So the lowest value is 0.For a Poisson distribution with parameter l=1 (when it is very skew), the probability of the lowest two values, 0 and 1, is 0.368 each and the probability tails off rapidly for higher values.
Can a probability of some event be negative?
no
What is the significance of negative values of voltage and current?
What is the significance of negative values of voltage and current?Negative values show direction and that is the significance
Why cant a negative fraction represent a probability?
Probability is a ratio of two counts: both of which MUST be positive. Their ratio cannot be negative.
