What is the mean of the sampling distribution of X Bar? The Sampling Distribution of the Sample Mean. If repeated random samples of a given size n are taken from a population of values for a quantitative variable, where the population mean is μ (mu) and the population standard deviation is σ (sigma) then the […]

Why Subduction Zone trenches and mountain ranges are formed?
Why Subduction Zone trenches and mountain ranges are formed? Various formations such as mountain ranges, islands, and trenches are caused by subduction and the volcanoes and earthquakes it triggers. Subduction zones are mainly located in the Pacific Ocean. This is because seafloor spreading – the process by which new oceanic crust is created – occurs […]
What is the largest solid conductor listed in the wire tables?
What is the largest solid conductor listed in the wire tables? copper Which of the following conductors when installed in a raceway is permitted to be a solid conductor? Yes, a solid bare copper 10 AWG equipment grounding conductor IS permitted in a metallic raceway. However, a bare aluminum conductor is NOT permitted in a […]
What is the amount of force that a braking system requires the driver to apply to stop a vehicle?
What is the amount of force that a braking system requires the driver to apply to stop a vehicle? On a hydraulic brake system, the driver generates force by pressing on the brake pedal. The force is then amplified by the pedal, booster and master cylinder. The driver will modulate the pressure on the pedal […]
Does sewage go into Lake Michigan?
Does sewage go into Lake Michigan? In 2018, the agency overseeing Milwaukee’s system, which serves 1.1 million people and 28 communities, saw six combined sewer overflows — the most events since 1999. Those overflows sent 1.2 billion gallons of stormwater and untreated sewage into rivers, canals and a stream that drain into Lake Michigan. Is […]
How is refrigerant cooled?
How is refrigerant cooled? As refrigerant absorbs heat from indoor air, it transitions from a low-pressure gas to a high-pressure liquid. Air conditioning components send the refrigerant outside where a fan blows hot air over the coils and exhausts it to the exterior. The refrigerant then cools down and turns back into a low-pressure gas. […]
What is the safety measurement system?
What is the safety measurement system? The Safety Measurement System (SMS), a branch of the Federal Motor Carrier Safety Administration (FMCSA), identifies and intervenes with drivers who have demonstrated unsafe driving behavior. It uses seven distinct categories, known as BASICs, to identify, categorize, and rank drivers to prioritize for intervention. Who is affected by the […]

What is the difference between single crystal and polycrystal?
What is the difference between single crystal and polycrystal? Single crystals have infinite periodicity, polycrystals have local periodicity, and amorphous solids (and liquids) have no long-range order. A polycrystalline solid or polycrystal is comprised of many individual grains or crystallites. Why are polycrystalline materials stronger than single crystals? Since plastic deformation of a single grain […]
