A random sample of 108 customers was taken in a shopping mall. The mean number of items purchased by the customers in the sample was 3.9 with a standard deviation of 1. The median was 4.4, and the mode was 4. A graph shows that the distribution of the data is highly skewed to the left. A store manager wants to calculate the probability that a customer will purchase at least 4 items. Is the statement below true?

The probability cannot be accurately determined using the mean, standard deviation, or z-score table.

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

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
