2013-2014 LABORATORY WORK # 2 THE BINOMIAL DISTRIBUTION Submitted by: Briones‚ Kristelle R. Mangrobang‚ Jonathane Submitted to: Prof. Ernesto Adorio January 2014 Description: Our instructor instructed to put tabulate the Binomial Distribution for various n given the values of p which are (0.1‚ 0.2‚ 0.3‚ 0.4‚ 0.5‚ 0.6‚ 0.7‚ 0.8 and 0.9). The binomial distribution is the discrete probability distribution of the number of successes in a sequence of n independent

X-bar The topic of 4th seminar&lab is the average of the population that has a certain characteristic. This average is the population parameter of interest‚ denoted by the greek letter mu. We estimate this parameter with the statistic x-bar‚ the average in the sample.

The hardest part about this assignment is finding the center line. The center line is always X-bar-bar. (An x with two bars above it). It’s the mean of all the sample means. I’ve attached an Excel spreadsheet showing how to calculate X-bar-bar. First‚ you find the average of each sampe. There were four in this case. The average is at the bottom. Then you take those four numbers and find the average for those. I rounded up to 5.1 to make it easier to graph. So X-bar-bar = 5.1. Once you X-bar-bar

The distribution of the earth’s population across the globe is uneven. The earth contains many different environments with only few parts suitable for human habitation. Around 70% of the earth’s surface is covered in water‚ leaving only 30% as land; however within this portion exist many physical features that restrict human habitation. Only around 11% of the earth’s surface poses no serious threat to human settlement and 80% of the world’s 6.7 billion people live on 10% of the earth’s surface

Population distribution of Brazil: Brazil is a LEDC with most of its population living in coastal areas‚ with the south being more densely populated. Density: 22/km2 Population: 205‚716‚890 Climate: mostly tropical‚ but temperate in south (cooler in summer‚ warmer in winter) -North-west: covered in tropical rainforest‚ hot and humid climate‚ poor soils‚ little known natural resources‚ difficult transport‚ lacks basic services such as health care‚ education and electricity.

Essay Title: Describe and explain the population distribution of Brazil. Population distribution means the pattern of where people live. The world’s population distribution is very uneven. Places which are sparsely populated contain few people and places which are densely populated contain many people. Sparsely populated places tend to be difficult places to live. These are usually places with hostile environments e.g. Antarctica. Places which are densely populated are habitable environments e.g

Population distribution is how people are dispersed over a given area. Population distribution is measured by persons per square kilometer. An area (or country) can be densely populated‚ which means there is a high concentration of persons per square kilometer‚ or sparsely populated‚ which means there is a low concentration of persons per square kilometer. The distribution of population can be influenced by both physical and human factors. Physical factors include relief‚ climate‚ vegetation‚ soil

The majority of Australia’s population is distributed along the coastline. The current population of around 20 million is concentrated mainly in the large coastal cities of Sydney‚ Melbourne‚ Brisbane‚ Perth and Adelaide. Brisbane and Sydney are located on the south-eastern coast consecutively. From the bottom right to the bottom left of the continent‚ located on the south-eastern to south-western coasts are Melbourne‚ Adelaide and Perth‚ respectively. These concentrated cities then branch

Weston Materials‚ Inc.‚ a national manufacturer of unattached garages‚ reports that it takes two construction workers a mean of 32 hours and a standard deviation of 2 hours to erect the Red Barn model. Assume the assembly times follow the normal distribution. a. Determine the z values for 29 and 34 hours. What percent of the garages take between 32 hours and 34 hours to erect? z(29) = (29-32)/2 = -3/2 z(34) = (34-32)/2 = 1 z(32) = 0 P(32 < x < 34) = P(0< z < 1) = 0.34 b. What percent of the
