Question

The expected value of a statistic minus the value of the population parameter?

a.
Standard error

b.
Sampling error

c.
All of these

d.
error

e.
Non of these​

Answer 1

Answer:

The formula is simply p where n is the number of observations and p is the probability of a success in each individual trial (note: no n in the formula).

One proof is first to do the case n = 1, then use the rule that the expectation of a sum is the sum of the expectations (np), and finally divide by n to convert the sum to the mean.

Answer 2

Answer:

b. sampling error is the expected value of statistic minus the value of the population parameters.
