In two common species of flowers, a and b, the proportions of flowers that are blue are pa and pb , respectively. Suppose that independent random samples of 50 species-a flowers and 100 species-b flowers are selected. Let pˆa be the sample proportion of blue species-a flowers and pˆb be the sample proportion of blue species-b flowers. What is the mean of the sampling distribution of pˆa−pˆb ?.

Answers

Answer 1

The mean of the sampling distribution is [tex]{p_{a}}-p__b}[/tex]

The mean of a sampling distribution is the population mean from which values are sampled. For a population of mean μ, the mean of the sampling distribution is [tex]\mathbf{ \mu_x}[/tex]

[tex]\mathbf{\mu_x = \mu}[/tex]

From the parameters given:

Suppose that independent random samples of 50 species-a flowersand 100 species-b flowers are selected

where;

[tex]\mathbf{\hat p_a}[/tex] = sample proportion of blue specie-a[tex]\mathbf{\hat p_b}[/tex] = sample proprotion of blue specie-b

The mean of the sampling distribution of [tex]\mathbf{\hat p_a -\hat p_b}[/tex] is [tex]{p_{a}}-p__b}[/tex]

Those who are more physically capable of surviving, maturing, and reproducing. On the other hand, those who lack this fitness either do not live long enough to reproduce or have fewer children than their counterparts.

Because the "fittest" organisms—those most adapted to their environment—are the ones that reproduce most successfully and are most likely to pass on their qualities to the next generation, natural selection is sometimes summed up as "survival of the fittest."

This means that if an environment changes, qualities that help people survive in it will eventually adapt, or develop. Natural selection was a potent force.

Which statement best explains a difference between a character vs. Self conflict and a character vs. Character conflict?.

Answers

Answer: A character vs. Self conflict and a character vs. Character conflict are two different types of conflicts commonly found in literature. Here's an explanation of the difference between the two:

Character vs. Self Conflict:

Character vs. Self conflict, also known as internal conflict, occurs when a character struggles with their own thoughts, emotions, beliefs, or decisions. It is a psychological or emotional struggle within the character's mind. The conflict arises from a moral dilemma, self-doubt, guilt, fear, or any internal obstacle that the character must overcome.

Example: A protagonist who is torn between following their principles and doing what is morally right, even if it puts them in danger or conflicts with their personal desires, is experiencing a character vs. Self conflict.

Character vs. Character Conflict:

Character vs. Character conflict, also known as external conflict, involves a struggle between a character and an external force, typically another character. This type of conflict arises from opposing goals, interests, or ideologies between two or more characters. The conflict is usually more overt and may involve verbal or physical confrontations.

Example: In a story, the hero and the villain engage in a battle of wits and physical confrontation. This conflict is an example of character vs. Character conflict.

In summary, the key difference lies in the source of the conflict. Character vs. Self conflict is internal, involving the character's own thoughts and emotions, while character vs. Character conflict is external, involving clashes between different characters and their opposing objectives or viewpoints. Both types of conflict play essential roles in developing the plot and character arcs in a story.
