Ten countries were randomly selected from the list of 129 countries in theCountry. The countries are compared with respect to their gross nationalproduct per capita, an indicator of the average income level of each country.Researchers have found that people in countries with higher income levelstend 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 statisticallysignificant at the 0.05 level of significance.

In a study comparing banks in two countries, a sample of 142 matched pairs of banks was formed. Each pair contained one bank from country x and one from country y. The pairings were made in such a way that the two members were as similar as possible in regard to such factors as size and age. The ratio of total loans outstanding to total assets was calculated for each of the banks. For this ratio, the sample mean difference (country x - country y) was 0.0579, and the sample standard deviation of the differences was 0.3086. Test, against a two-sided alternative, the null hypothesis that the two population means are equal. (Assume α = 0.01.) Click the icon to view the critical values of the Student's t distribution.

An experiment was conducted to compare the effectiveness of four training programs, namely, A, B, C, and D in training assemblers of a piece of electronic equipment. Twenty employees were randomly selected and assigned to each program, that is, five employees per program. After completion of the training courses, each person was required to assemble four pieces of equipment, and the length of time (in secs) to complete the assembly was recorded. The summary of the data gathered is recorded in the table. At α=0.10, test for the hypothesis that the assembly times for people trained are the same for the four programs.
