Apart from national income‚ health indicators can also measure the standard of living between countries. From table 6‚ it can be seen that the under-five mortality rate‚ per thousand of the population in Tanzania is 15 times greater than USA. It means that the childcare in Tanzania is poorer and lacked development‚ leading to a lower standard of living. Take life expectancy at birth as another example‚

university reported admission statistics for 3339 students who were admitted for freshmen for the fall semester of 1998. Of these students‚ 1590 had taken the Scholastic Aptitude Test (SAT). Assume the SAT verbal scores were normally distributed with a mean of 530 and a standard deviation of 70. a – What percentage of students were admitted with SAT verbal scores between 500 and 600? b - What percentage of students were admitted with SAT verbal scores of 600 or more? c - What percentage of students

The middle ranked breaking force is 1735 pounds. The differences between the smallest and largest breaking force is 348 pounds. The average difference between each value and the mean is 89.55 pounds. c. The distribution is skewed to the left because the mean is less than the median. d. All the observations in the sample have breaking force
