18. Based on a simple random sample of one hundred an analyst estimates the average hourly wage earned by workers in a city to be $30 and computes the margin of error to be $5. Can we conclude from this that most workers there earn between $25 and $35 per hour? Is the right interpretation for the margin of error? 23.

Module 1 Suppose you hear an "old-timer" say‚ "Why‚ in my day‚ kids were much more respectful and didn’t cause as much trouble as they do nowadays!" Formulate a hypothesis related to this statement that you could test. How would you test it? The old-timer are the older person in their 70s or 80s at this time. I would compare the age when this old timer is raising his own children . what actually age he may be‚ let say‚ 25 years old if he was born in 1940 by the year 1965 to determine respectfulness

Chapter 3 Fluid Statics: Definitions Statics: ∑F = 0. In statics we have only pressure as surface force and weight as body force. Thus‚ when fluids are still‚ the pressure is balanced by the fluid weight. No relative motion between adjacent fluid layers. Shear stress is zero Only _______ can be acting on fluid surfaces Gravity force acts on the fluid (____ force) Applications: Pressure variation within a reservoir Forces on submerged surfaces Buoyant forces 9/4/2013 1 Pressure Pressure is defined
