Question

14 - It is known that the rate of defective products in the First Factory is 0.08 and the rate of defective products in the second Factory is 0.06. 40 products from the first factory and 36 products from the second factory are randomly selected. Since the standard error of the difference between the defect rates is 0.0584, what is the probability that the difference between the defective product ratio of the sample taken from the first factory and the defective product rate of the sample taken from the second factory is more than 0.03? (normal distribution)

A) 0.4325 B) 0.1356 C) 0.3628 D) 0.1263 E) 0.7452

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.
