1.76 Peace Corps Volunteers. The Peace Corps is an indepen- dent U.S. government agency that provides trained volunteers for countries requesting assistance. According to Peacecorps.org, as of September 2012, volunteers currently serve in about 76 different host countries. The average age of a volunteer is about 28 years old. The following table reports the percentage of total volunteers serving by geographic region. Percent of volunteers Region Africa 43% Latin America 21% Eastern Europe/Central Asia 15% Asia 10% Caribbean 4% North Africa/Middle East 4% Pacific Islands 3% a. Use the table to design a procedure for obtaining a stratified sam- ple (with proportional allocation) of 50 Peace Corps volunteers. b. If stratified random sampling with proportional allocation is used to select the sample of 50 Peace Corps volunteers, how many would be selected from the Caribbean?
In a researcher’s action research, she seeks to investigate whether a particular intervention works for teaching a mathematical concept. She organizes a diagnostic test (pre-test), taught with her intervention and then did a post-test. The recorded scores for ten students is in the table below: Student ID 01 02 03 04 05 06 07 08 09 10 Pre-test 66 49 63 70 71 65 75 88 87 51 Post-test 69 50 61 72 78 66 75 89 86 54 I. Draw a scatter plot for the observed scores and superimposed in it a least square regression line. ii. Compute the pearson product moment coleration for the two test and interpret your results.
