We wish to know about the world's population. Is it really increasing? If so, at whatrate is it increasing? To answer this question, one of the things we would need to know about is the difference between birth and death rates. What is the average difference between birth and death rates throughout the world? Is there a significant difference between the birth rates and death rates? Your task is to use the data in the table below to find out. Birth and death rates are year 2014 estimates and the units are "per 1000 people". Country Birth rate Death rate Differences USA 13.42 8.15 -5.27 Australia 12.19 7.07 -5.12 Kazakhstan 19.61 8.31 -11.3 Bolivia 23.28 6.59 -16.69 Suriname 16.73 6.13 -10.6 Mauritania 31.83 8.35 -23.48 Zimbabwe 32.47 10.62 -21.85 Turkey 16.86 6.12 -10.74 Mean -13.131 Sample Std. Dev. 6.94 Fill in the differences, mean of the differences, and sample standard deviation of the differences in the table above Conduct a paired t-test to see if there is a significant difference between birth rates and death rates. Write down all of the steps taught in this class and use a 196(0.01) significance level. Your response should include: 1. the null and alternative hypotheses 2. any assumptions you make 3. any calculator functions (including relevant input and output) you use 4. the outcome of the test
