**DTAL – AP Statistics - Unit 1 - 22-23****Instructor:** Michael, Danaysha---**Overview:**You are given two normally distributed populations:- **Population X:** Mean ($\mu$) = 50 and Standard Deviation ($\sigma$) = 12- **Population Y:** Mean ($\mu$) = 75 and Standard Deviation ($\sigma$) = 15---**Question:**Which of the following has the greatest area?1. Area above 65 in Population X2. Area below 60 in Population Y3. Area below 25 in Population X4. Area above 80 in Population Y5. Area between 75 and 90 in Population Y---*Note: The question requires understanding which specified area under the given normal distributions is greatest. This involves calculating probabilities based on the standard normal distribution curves using the provided means and standard deviations.*

Normal probability calculated using calculator.

Looking for the answers and explanation to questions 1,2 and 3 below. Histogram is attached so no need to run it. Your boss asks you to gather all data regarding pounds of waste across all areas identified. You go through the store archives and find data over the past 100 weeks. The weekly pounds of waste is in the chart below (treat this as population data). She wants to know if the data is normally distributed and for you to explain process variability to her. You decide to run a histogram to visually inspect for data normality. 1.) Explain to your boss the histogram and the “shape” of the curve. 2.) Is it normally distributed? 3.) Does it appear that there is high or low variability in the waste numbers? Explain to your boss.
