Concept explainers
On average, every minute of every day, 158 babies are born. The bar graph represents the results of a single day of births, deaths, and population increase worldwide. Exercises 25-26 are based on the information displayed by the graph.
Each day, the number of births in the world is 84 thousand less than three times the number of deaths.
a. If the population increase in a single day is 228 thousand, determine the number of birth and deaths per day.
b. If the population increase in a single day is 228 thousand, by how many millions of people does the worldwide population increase each year? Round to the nearest million.
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 the entire U.S. population (315 million)?

- Please solve the following Probability Problem, please show all work and solve what is asked: HW 1.w. (Special game)The atmosphere has heated up and a fight erupted! There are n + 1players and somebody threw the first punch. Once a person is punched,they punch another person in the group at random. What are the oddsthat after m iterations:a) Nobody punches the person who started it?b) Nobody gets punched twice?Now take it up a notch: imagine the first person punched N other peopleat random, and once someone gets punched, they punch another N peoplein the group at random, and so on. Again, what are the odds that afterm iterations:a) Nobody punches the person who started it?b) Nobody gets punched twice?arrow_forwardQ1. A chest of drawers has 3 drawers. Each drawer has 2 boxes. The boxes of one drawer contain a silver coin in each respectively, the boxes of another a gold coin in each box, and the boxes of the third drawer a gold and a silver coin, respectively. A drawer is selected at random and a box from the drawer is selected at random and opened. The coin is found to be silver. What is the probability that the coin in the other box is gold?

Apply cd command to tell STATA the filepath associated with your "favorite folder" (use the same name for the favorite folder that we have been using in class) Apply log using command to tell stata that you are creating a log file to record the codes and the outcomes of these codes. Make sure your log file is called loghwa1_W25.smcl. Do not forget to include the replace option. iii. Get help for the "regress" command & include a screenshot of the outcome of this code iv. V.
