Question 2 Ten countries were randomly selected from the list of 129 countries in the Country. The countries are compared with respect to their gross national product per capita, an indicator of the average income level of each country. Researchers have found that people in countries with higher income levels tend to live longer than do people in countries with lower income levels. In addition, birth rates tend to be higher in countries with lower incomes, with birth rates declining as countries become better off economically. a. Use this data to determine the Spearman rank correlation of GNP with (i) life expectation, and (ii) the birth rate. b. Test to determine whether the correlation of ranks is statistically significant at the 0.05 level of significance.
