What value of Z from the standard normal distribution has an area probability to the right equal to 0.0643?
z = 1.52 (approx)
When a population distribution is right skewed is the sampling distribution normal?
No, as you said it is right skewed.
What is the math shape when it looks like a bow?
It could be a Gaussian curve (Normal distribution) rotated through a right angle.It could be a Gaussian curve (Normal distribution) rotated through a right angle.It could be a Gaussian curve (Normal distribution) rotated through a right angle.It could be a Gaussian curve (Normal distribution) rotated through a right angle.
What is the difference between a probability mass function and a probability density function?
The probability mass function is used to characterize the distribution of discrete random variables, while the probability density function is used to characterize the distribution of absolutely continuous random variables.

What are skews in math?
In math, skewness is a measure of the asymmetry of a probability distribution. A distribution is considered right-skewed if the tail on the right side is longer or fatter than the tail on the left side, and vice versa for left-skewed distributions. Skewness can give insight into the shape of a dataset and how it deviates from a symmetrical distribution like the normal distribution.
Can a normal distribution curve be symmetric or left-skewed or right-skewed?
Symmetric
The F-distribution is symetrical around mean zero True or False?
The F-distribution is either zero or positive, so there are no negative values for F. This feature of the F-distribution is similar to the chi-square distribution. The F-distribution is skewed to the right. Thus this probability distribution is nonsymmetrical.
If the area to the left of x in a normal distribution is 0.161 what is the area to the right of x?
It is 0.839
What is the area under the normal distribution curve to the right of z that equals 3.24?
0.0006 (approx).
How does the mean affect the graph of a normal distribution?
It determines the location of the graph: left or right - but not its shape.
If the area to the left of x in a normal distribution is 0.123 what is the area to the right of X?
It is 0.877
What does the term physical distribution refer to?
probability distribution
