Question

Which propertie(s) make the Chi-Squared distribution different than the standard normal distribution?

(You may have more than one answer....select all that apply)

Group of answer choices

1.The Chi-squared distribution is right-skewed

2.The Chi-squared distribution is centered around the mean of 0

3.The Chi-squared distribution approaches, but does not cross, the positive horizontal axis

4.The Chi-squared distribution only represents positive values of the variable

5.The area under the curve of the chi-squared distribution. over an interval of values, is equal to the probability of those values.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
