Simulate 100 random samples of size 100 from normal distribution with mean and standard deviation as 120 and 24 respectively to perform t test to each of sample to find out whether the mean birth weight from the hospital is lesser than the national average and state the proportion of samples which supported the hypothesis.

Answer 1

Question

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.
