On average, every minute of every day, 151 babies are born. The bar graph represents the results of a single day of births, deaths, and population Daily Growth of World Population increase worldwide. Births Each day, the number of births in the world is 70 thousand less than three times the number of deaths. Complete parts (a) through (c). Deaths Population Increase 10 200 30 400 Number of People (thousands) a. If the population increase in a single day is 218 thousand, determine the number of births and deaths per day. There are thousand births per day. There are thousand deaths per day. b. If the population increase in a single day is 218 thousand, by how many millions of people does the worldwide population increase each year? million (Round to the nearest million as needed.) c. Based on your answer to part (b), approximately how many years does it take for the population of the world to increase by an amount greater than 315 million? O years (Round up to the nearest year.)
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
