Question

Computer software generated 500 random numbers that should look as if they are from the standard Normal distribution. They are categorized into five groups: (1) less than or equal to -0.6, (2) greater than -0.6 and less than or equal to -0.1, (3) greater than -0.1 and less than or equal to 0.1, (4) greater than 0.1 and less than or equal to 0.6 and (5) greater than 0.6 the counts in the five groups are 140, 101, 43, 76, and 140, usint table A. Then compute the expected number for each interval for a sample of 500. Finally, preform the goodness-of-fit test and summarize your results

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.
