If a data set has mean of 150 and a standard deviation of 25, what is the z-score of an element with a value of 250?

Z-score is 4

Step-by-step explanation:

N(150, 25^2)

Use z-score formula (can be found from internet with miu and sigma symbol)

b is the answer that makes most sense

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
