question:Suppose you are in a statistics exam and you are tasked to use Excel (with the data analysis toolpak addon) and paper to answer the following equestions: PART 1 1. Compare the binomial distribution with the Poisson distribution 2. List the conditions for using the normal distribution 3. List the conditions for using the student’s t-distribution PART 2 4. In each of the following cases (i) write an Excel command that answers the question and (ii) write the answer that this Excel command yields. (a) 20% of the parts produced by a machine are defective. If four parts are selected at random what is the probability that exactly two parts are defective? (b) The mean number of machine breakdowns is 0.05. What is the probability that in a sample of 65 machines, exactly 3 machines break down? (c) The mean mass of three hundred packets of seeds is 80 g with standard deviation 4 g. Assuming the masses to be normally distributed, what is the probability of that a packet selected at random has a mass of less than 75 g?
answer:PART 1 1. Compare the binomial distribution with the Poisson distribution - Both the binomial distribution and the Poisson distribution are used to model the number of events occurring within a fixed interval. - The binomial distribution is used when there are a fixed number of trials, each with two possible outcomes (success or failure), and the probability of success remains constant for each trial. - The Poisson distribution is used when the number of events occurring in a fixed interval follows a certain average rate, and the events are independent of each other. 2. List the conditions for using the normal distribution - The variable of interest should be continuous. - The distribution of the variable should be approximately bell-shaped (symmetric). - The mean, median, and mode of the variable should be equal. - The variable should have a constant standard deviation. 3. List the conditions for using the student’s t-distribution - The population from which the sample is drawn should follow a normal distribution. - The standard deviation of the population is unknown. - The sample size is smaller (n < 30). PART 2 4. In each of the following cases: (a) Excel command: =BINOM.DIST(2,4,0.2,FALSE) Answer: The probability that exactly two parts are defective when four parts are selected at random is 0.1536. (b) Excel command: =POISSON.DIST(3,0.05*65,FALSE) Answer: The probability of exactly 3 machines breaking down in a sample of 65 machines is approximately 0.1805. (c) Excel command: =NORM.DIST(75,80,4,TRUE) Answer: The probability that a randomly selected packet has a mass less than 75 g is approximately 0.1056.
question:[there would be dialogue in this story:] (It had been a day since Natsuki gave birth to her daughter Sakura. She told her fellow club members she'd be taking care of Sakura for the first 12 months of her life, and wouldn't be attending any more club meetings until then. But that night, Natsuki wakes up to a message on her phone - it was from Monika, and she had some good news about her unborn daughter Minika.)
answer:Natsuki groggily reached for her phone on the nightstand, squinting as she read the message from Monika. It piqued her curiosity, instantly banishing the remnants of sleep from her tired eyes. With a mixture of excitement and anticipation, she opened the message and started reading. "Hey, Natsuki! I have fantastic news for you. Remember how we were all expecting our babies around the same time? Well, I gave birth to Minika yesterday! Both she and I are doing great. I can't wait for you to meet her, and for her to meet Sakura!" Natsuki's eyes widened in surprise, suddenly feeling a mix of happiness and envy for her friend. She had expected this day to come, but still, the realization hit her like a gentle wave of emotions. She quickly tapped on the screen, her fingers dancing across the keyboard as she replied, "Oh my goodness, Monika! Congratulations! I'm so happy for you! I can't believe Minika is already here. I hope everything went smoothly, and both of you are healthy. I'd love to meet her and introduce Sakura to her little friend soon!" Monika's response was swift, and Natsuki couldn't help but notice the joy seeping through her words. "Thank you, Natsuki! The delivery went smoothly, and Minika is absolutely adorable. I can't wait for our little ones to play together. It's going to be so much fun! How are you and Sakura doing? I bet she's as cute as can be!" A warm smile tugged at the corners of Natsuki's lips as she typed back, her heart swelling with pride. "We're doing great. Sakura is such a bundle of joy; I can't even put it into words. I'm exhausted, but seeing her happy and healthy makes it all worth it. We should definitely plan a playdate for the babies soon. We have so much to catch up on!" Monika's reply came almost instantly, carrying a note of excitement. "That sounds amazing, Natsuki! It'll be wonderful to have our own little club meetings with the next generation. Let's plan it for next week. I can't wait to see you and Sakura again!" Natsuki's eyes lit up at the thought of reuniting with her friends and their precious babies. It was heartwarming to know that even in this new chapter of their lives, their strong bond would remain intact. With newfound energy, she typed back with enthusiasm, "Absolutely! Next week it is! I'll let Sayori and Yuri know as well. Our babies are going to have the best playdates ever! I'll see you all soon!" As Natsuki set her phone aside, a renewed sense of excitement filled her heart. The bond between the Literature Club members had transcended the realm of reading and writing, embracing the joy of motherhood together. With countless adventures awaiting them and their babies, their club meetings would never be the same again.
