question 32

Multiple Choice

An electron is accelerated from rest by an electric field.After the acceleration,the electron is injected into a uniform magnetic field of 1.27 $\times$ 10^-3 T.The velocity of the electron and the magnetic field lines are perpendicular to one another.The electron remains in the magnetic field for 5.00 $\times$ 10^-9 s.The angle between the initial electron velocity and the final electron velocity is

• A)1.1 rad
• B)5.8 \(\times\) 10^-2 rad
• C)8.68 \(\times\) 10^-2 rad
• D)6.5 \(\times\) 10^-2 rad
• E)2.3 rad

Parametric Tests

Statistical tests based on assumptions about the population distribution from which the sample is drawn, typically involving parameters like mean and standard deviation.

Normal Approximation

A method used to estimate the shape of a binomial distribution using a normal distribution when the sample size is large.

Sign Test

A non-parametric test used to determine if there is a statistically significant difference between paired or matched samples by examining the signs of differences without assuming any particular distribution.
