The option that represents the conditions that will create a biased estimator of a population parameter is;

D: The expected value of the estimator is not equal to the population parameter.

<h3>Biased and Unbiased Estimators</h3>

Usually in statistics research, there is what we call population parameters and sampling parameters.

The population parameters represent the full pool from which a sample can be taken while the sample parameters are gotten from the sample taken from the population.

Now, a statistic will be referred to as an unbiased estimator of a population parameter if the mean of the sampling distribution of the statistic is equal to the value of the population parameter.

In contrast to an unbiased estimator, a biased estimator of a population parameter is referred to as such if the mean of the sampling distribution of the statistic is not equal to the value of the population parameter.

The missing options are;

A. The sampling distribution of the estimator is skewed to the left.

B. The sampling distribution of the estimator is skewed to the right.

C. The sampling distribution of the estimator is not the same shape as the distribution of the population parameter.

D. The expected value of the estimator is not equal to the population parameter.

E. The variability of the sampling distribution of the estimator is not equal to the variability of the population parameter.

<h3>Understanding Change in Momentum</h3>

Formula for change in momentum is;

ΔP = m(v - u)

Now, this change in momentum is also equal to impulse which has the formula; Impulse = Force(F) × Time(t)

I = F × t

Thus;

m(v - u) = F × t

Now, we are given;

Force exerted on the object and the time interval. Thus;

ΔP = F × t

Thus, the student has enough information to find the change in momentum

The missing options are;

a. The mass of the object.

b. The final speed of the object MOH 5000

c. The distance fallen by the object

d. The student has enough information to make the determination

Lana71 [14]

Hamilton thinks judges should be appointed permanently rather than on a periodic basis because periodic appointments would destroy a judge’s independence.

Alexander Hamilton was an American revolutionary. He was also a statesman and the Founding Father of the United States. He played a key role in promotion and interpretation of the constitution.

Permanent appointments would help to regulate more as well ensure greater independence of the judge.

Periodic appointment on the other hand would destroy a judge independence as he/she can be transferred or impeached anytime that fosters insecurity and lack of motivation to work.

Thus, permanent appointments is the only option.

There are different variations in population size. The best reason why the simulation of the sampling distribution is not approximately normal is that The sample size was not sufficiently large.

<h3>What takes place if a sample size is not big enough? </h3>

When a sample size taken by a person or a researcher is not big or inadequate for the alpha level and also analyses that one have chosen to do, it will limit the study statistical power.

Due to the above, the ability to know a statistical effect in one's sample if the effect are present in the population is greatly reduces.

See full options below

Which of the following would be the best reason why the simulation of the sampling distribution is not approximately normal?

A The samples were not selected at random.

B The sample size was not sufficiently large.

с The population distribution was approximately normal.

D The samples were selected without replacement.

E The sample means were less than the population mean.
