Question

TRUE OR FALSE

a. When the assumptions of distributions are met, the parametric tests are more powerful than non-parametric tests
b. In Poisson distribution, the mean is equal to its variance

c. The Main objective of Statistical inference is to make inferences about the population-based n the whole set of population values

d. The Variable X defined X~N(0,1) is called the Standard Normal Distribution

e. Welch Test for testing two population means does not assume that the variances are equal

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.
