Question

A manager at an assembly line is trying to seewhat proportion of their products are defective. The manager does a quality ceckby sampling 132 of its products. the manager finds that 16% of the 132 products are defective. Assume the proportion of defective products followed a normal distribution

A- create a 80% confidence interval for the percent of defective products for the company

B- interpret the confidence interval that was found for part A

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.
