Can Standard Deviation be greater than 100?
Yes. It can have any non-negative value.
Is it possible to have a probability greater than 100?
It is not possible to have a probability greater than 1. All probabilities are between 0 and 1, inclusive.
When a number cube is rolled once what is the probability of getting an odd number greater than five?
it depends on how many numbers are on the number cube. if it only goes to 6, then the probability is 1/6. if it goes to 8 then the probability is 2/8. and so on and so on...
What does at least mean in math?
'At least' means equal to or greater than. This meaning is not restricted to maths; it is one of the common everyday meanings of the phrase.So if you have a question which, for example, tells you to calculate the probability of getting at least one head when a coin is flipped twice then it means:What is the probability of getting one or more heads when a coin is flipped twice.
An ordinary die is tossed four times what is the probability of obtaining a number greater than 4 at least once?
1 - (2/3)4 = 1 - 16/81 = 65/81 ≈ 80.25%
Why does a Uniform distribution have a greater standard deviation?
The answer depends on greater standard deviation that WHAT!
What does standard deviation tell about distribution and varity?
It is a measure of the spread of the distribution. The greater the standard deviation the more variety there is in the observations.
How does the standard normal distribution differ from the t-distribution?
The normal distribution and the t-distribution are both symmetric bell-shaped continuous probability distribution functions. The t-distribution has heavier tails: the probability of observations further from the mean is greater than for the normal distribution. There are other differences in terms of when it is appropriate to use them. Finally, the standard normal distribution is a special case of a normal distribution such that the mean is 0 and the standard deviation is 1.
Can a standard deviation be greater than its mean?
Yes - but the distribution is not a normal distribution - this can happen with a distribution that has a very long tail.
What is the difference between a general normal curve and a standard normal curve?
A standard normal distribution has a mean of zero and a standard deviation of 1. A normal distribution can have any real number as a mean and the standard deviation must be greater than zero.
Fora standard normal distribution what is the probability that z is greater than 1.75?
.0401
What is the probability that z (the standard normal distribution variable) is greater than 1?
It is 0.1587
We have a population with mean of 100 and standard deviation of 28 take repeated samples of size 49 and calculate the mean of each sample to form a sampling distribution Is it a Normal Distribution?
a) T or F The sampling distribution will be normal. Explain your answer. b) Find the mean and standard deviation of the sampling distribution. c) We pick one of our samples from the sampling distribution what is the probability that this sample has a mean that is greater than 109 ? Is this a usual or unusual event? these are the rest of the question.
Can standard deviation be greater than mean?
Standard deviation can be greater than the mean.
Can normal distribution be applied on discrete data?
Yes. The normal distribution is used to approximate a binomial distribution when the sample size (n) times the probability of success (p), and the probability of failure (q) are both greater than or equal to 5. The mean of the normal approximation is n*p and the standard deviation is the square root of n*p*q.
What is the z score of 1.0?
It is the value that is one standard deviation greater than the mean of a Normal (Gaussian) distribution.
Using the standard normal distribution find the probability that z is greater than 1.78?
0.0375
