Lamar collected a random sample of data about the number of letters in the full names of seventh graders at his school. His sample mean was 10.2
10.2. Lamar's teacher told him that the population mean is
12.4
12.4. Lamar thinks he did something wrong because his sample mean is not the same as the population mean.

Should Lamar be concerned?

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
