The fertility rate is the mean number of children born to a typical woman in the country, and the female literacy rate is the percentage of women at least 15 years old who can read and write. The table contains the female literacy rate (in percent) and the fertility rate (in numbers of children) for a random sample of 10 countries. Calculate the Spearman rank co-efficient. Country Female literacy Fertility Afghanistan 21 6.69 India 48 2.73 Sudan 51 4.72 Saudi Arabia 71 4.00 South Africa 86 2.20 China 87 1.73 Israel 94 2.41 Italy 98 1.28 United States 99 2.09 Poland 100 1.25

A sociologist studying fertility in France and Switzerland wanted to test if there was a difference in the average number of babies women in each country have. The sociologist obtained a random sample of women from each country. Here are the results of their test: Country Sample Size Mean SD France 100 1.85 1.3 Switzerland 100 1.65 1.2 At the alpha 0.05 level of significance, is there sufficient evidence to conclude that there is a difference in the average number of babies women in each country have?

The literacy rate for a nation measures the proportion of people age 15 and over who can read and write. The literacy rate for women in Afghanistan is 12%. Let X = the number of Afghani women you ask until one says that she is literate. What is the probability distribution of X? What is the probability that you ask exactly five women before one says she is literate? What is the probability that you must ask at least ten women? Find the mean and standard deviation of X.

World Population Growth The future size of the world population depends on how soon it reaches replacement-level fertility, the point at which each woman bears on average about 2.1 children. The graph shows projections for reaching that point in different years. Source: a. Estimate the average rate of change in population for each projection from 1990 to 2050. Which projection shows the smallest rate of change in world population? b. Estimate the average rate of change in population from 2090 to 2130 for each projection. Interpret your answer.
