Which of the following conditions will create a biased estimator of a population parameter?.
UkoKoshka [18]

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.

scientists say that researching genes will help find solutions for diseases that affect humans. is this true? Give reasons for y
Nataliya [291]
When genetic molecules are broken down and deciphered under a large scale then the defects can be magnified and researched and further stopped. Hopefully with the scientific advancements at hand and with enough people to come forward to participate in the study these diseases and genetic defaults will cease.

What it means that [If x is a factor of p(x), what is the value of k?]
kompoz [17]

Answer:

k = -4

Explanation:

Given

P(x) = (3x^2 - 5)(x + k) - 20

x is a factor

Required

Solve for k

x is a factor means that the polynomial can be divided successfully by x.

In other words, x is a zero of the polynomial.

i.e.

x = 0 and P(x) = 0

Substitute 0 for x in P(x)

P(x) = (3x^2 - 5)(x + k) - 20

P(x) = (3*0^2 - 5)(0 + k) - 20

P(x) = (0- 5)(k) - 20

P(x) = (-5)(k) - 20

P(x) = -5k - 20

Substitute 0 for P(x)

0 = -5k - 20

Collect Like Terms

5k = - 20

Divide both sides by 5

k = -4
