A bank branch located in a commercial district of a city has the business objective of developing an improved process for serving customers during the noon-to-1 p. m. lunch period. The waiting time, in minutes, is defined as the time the customer enters the line to when he or she reaches the teller window. Data collected from a sample of 15 customers during this hour are stored in Bank1. Suppose that another branch, located in a residential area, is also concerned with the noon-to 1 p. m. lunch period. A random sample of 15 customers is selected and the waiting times are collected and stored in Bank2.a. Is there evidence of a difference in the variability of the waiting time between the two branches? (Use alpha = 0.05).b. Determine the p-value in (a) and interpret its meaning. c. What assumption about the population distribution of each bank is necessary in (a)? Is the assumption valid for these data?d. Based on the results of (a), is it appropriate to use the pooled-variance t test to compare the meansWaiting Bank 1 Time4.215.553.025.134.772.343.543.2 04.506.100.385.126.466.193.79Waitin g Bank 2 Time9.665.908.025.798.733.828.018.3 510.496.685.644.086.179.915.47of the two branches?

First to answer all gets a donation question 3(multiple choice worth 1 points) (04.01 lc) which of the following levels is lower than cells in the hierarchy of organization of living things? molecules organs organ systems tissues question 4(multiple choice worth 1 points) (04.01 lc) which of these represents an individual form of life such as an animal, plant, or single-celled life form? organ organism organ system tissue question 5(multiple choice worth 1 points) (04.03 lc) what are the green structures inside plant cells where photosynthesis takes place called? chloroplast mitochondrion nucleus vacuole question 6(multiple choice worth 1 points) (04.03 lc) which of the following best matches a part of a living cell with the function it performs? cytoplasm: fluid which carries the nucleus and other organelles vacuole: fluid which carries the nucleus and other organelles cytoplasm: directs all of the cell's activities vacuole: directs all of the cell's activities question 7(multiple choice worth 1 points) (04.03 mc) read the table below. organelles of plant cells present in both plants and animals present in plants but not animals small in animals but large in plants organelle a organelle b organelle c which statement is most likely correct? organelle a is chloroplast, organelle b is cytoplasm, and organelle c is nucleus. organelle a is mitochondrion, organelle b is cytoplasm, and organelle c is nucleus. organelle a is cell wall, organelle b is chloroplast, and organelle c is mitochondrion. organelle a is mitochondrion, organelle b is chloroplast, and organelle c is vacuole. question 8(multiple choice worth 1 points) (04.03 mc) what will most likely happen in the absence of a nucleus? genetic information will not be transmitted by the cell. energy will not be released during cellular respiration. the cell will not store food, water, nutrients, and waste. the cell will lose its shape and structure.
