If the mean is 15.2 and the standard deviation is 0.9 What is the probability that x is greater than 16.1?

z = (x-mean)/sd = (16.1-15.2)/0.9 = 0.9/0.9 = 1
Pr(Z > 1) = 15.8655 %

Can the mean be less than the standard deviation?
In general, a mean can be greater or less than the standard deviation.
Why is the standard normal probability distribution unique?
a mean of 1 and any standard deviation

30 percent.
What is true of a standard normal probability distribution aA mean of 0 and a standard deviation of 1 b A mean of 1 and any standard deviation of 1 c Any mean and a standard deviatio?
a is true.
Is the mean for a set of data always greater than the standard deviation?
Yes; the standard deviation is the square root of the mean, so it will always be larger.
Can standard deviation be greater than mean?
Standard deviation can be greater than the mean.
What does it indicate if the mean is greater than the standard deviation?
It does not indicate anything if the mean is greater than the standard deviation.
Can the mean be less than the standard deviation?
In general, a mean can be greater or less than the standard deviation.
What is Normal of Standard Normal Probability Distribution?
with mean of and standard deviation of 1.
How do you calculate probability given mean and standard deviation?
The mean and standard deviation do not, by themselves, provide enough information to calculate probability. You also need to know the distribution of the variable in question.
Why is the standard normal probability distribution unique?
a mean of 1 and any standard deviation
Let X be a normal random variable with mean 10 and standard deviation of 5 What is the probability that X is greater than 12?
30 percent.
Assume that X has a normal distribution with mean equals 15.2 and standard deviation equals 0.9 What is the probability that X is greater than 16.1?
0.8413
What is Normal of probability distribution?
with mean and standard deviation . Once standardized, , the test statistic follows Standard Normal Probability Distribution.
How do you calculate mean and Median smaller then Standard deviation?
In the same way that you calculate mean and median that are greater than the standard deviation!
What is true of a standard normal probability distribution aA mean of 0 and a standard deviation of 1 b A mean of 1 and any standard deviation of 1 c Any mean and a standard deviatio?
a is true.
Difference between standard deviation and mean devition?
The mean deviation (also called the mean absolute deviation) is the mean of the absolute deviations of a set of data about the data's mean. The standard deviation sigma of a probability distribution is defined as the square root of the variance sigma^2,
