In a study of stress levels in U.S. army recruits stationed in Iraq, researchers obtained a complete list of the names of recrui
ts in Iraq at the time of the study. They listed the recruits alphabetically and then numbered them consecutively. One hundred random numbers between one and the total number of recruits were then generated using a random-number generator on a computer. The 100 recruits whose numbers corresponded to those generated by the computer were interviewed for the study. What is the population of interest in this study?
The population in a statistical study is determined by all the individuals that could be part of the study, that is, all the individuals that have common characteristics that make them individuals of interest to the researcher.
In the study of the previous statement, the population is made up of all recruits from the US Army. UU. in Iraq at the time of the study.
Surface area of a square pyramid is the area of the base + 4 times the area of one of the slanted sides.
Area of base = side length * side length
Area of side = (1/2) * side length * slant height
Don't forget that you have to multiply the area of the side by 4!
Step 1: 12 x 12 = 144 Step 2: 12 x 20 = 240 divided by 2 = 120 Step 3: 144 + 120 x 4
