AI Summary
This statistics assignment solution addresses problems involving probability distributions, hypothesis testing, and confidence intervals. The assignment begins with calculating probabilities using the binomial distribution, including finding the probability of exactly one defective component and at least two defective components in a box. It then applies a Poisson approximation to solve a probability problem for a larger batch of components. The second part of the assignment focuses on hypothesis testing using a chi-square test to determine if there's a difference in customer brand preference across different supermarkets. Finally, it calculates a 95% confidence interval for the true mean rent and determines the required sample size for a specified margin of error.
