According to one pollster, 43 % of people are afraid of flying. suppose that a sample of size 26 is drawn. find the value of standard error , the standard deviation of the distribution of sample proportions.

 0.0971

Step-by-step explanation:

Given : Sample size :

The percent of people are afraid of flying

Thus the proportion of people are afraid of flying

We know that the formula to find the standard deviation of the distribution of sample proportions is given by :-

Hence, the standard deviation of the distribution of sample proportions = 0.0971

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
