When a Neutron Decays, a Proton and an Electron Are

question 37

Multiple Choice

When a neutron decays, a proton and an electron are observed. When the electrons emitted from a sample of neutrons are observed, they are found to have different kinetic energies. This was accounted for by

• A) introducing a different particle, the neutrino.
• B) introducing the effect of gravity on the particles.
• C) including the kinetic energies of the neutron and proton.
• D) modifying the laws of conservation of momentum and energy.
• E) taking into account the uncertainties associated with Heisenberg's Uncertainty Principle.

In statistics, these are the estimated outcomes based on a regression model or other predictive model.

Coefficient of Determination

A statistical measure represented by R² that assesses the extent of variance in a dependent variable that is predictable from the independent variable(s).

Regression Model

A statistical framework that predicts the connection between a dependent variable and one or several independent variables.

Predictors

Variables used in statistical models to forecast outcomes or trends.
