The mean duration of television commercials on a given network is approximately bell-shaped with a mean of 75 seconds and standard deviation of 20 seconds. What is the duration of a commercial that has a z score of -2.5?

Answers

Answer 1

We can use the z-score formula to determine the duration of the commercial that has a z-score of -2.5.z = (x - μ) / σ

where

z = -2.5 (given)

μ = 75 (mean)

σ = 20 (standard deviation)

x = duration of commercial (unknown)

Substituting the values, we get:-2.5 = (x - 75) / 20

Multiplying both sides by 20, we get:-50 = x - 75

Adding 75 to both sides, we get:x = 25

Therefore, the duration of the commercial with a z-score of -2.5 is 25 seconds. This means that the commercial's duration is 2.5 standard deviations below the mean duration of commercials on the network.

what statement best fits with feminist theory?

Answers

Feminist theory encompasses a range of views, but a statement that is often associated with it is: "Gender inequality is a social construct that is perpetuated by patriarchal systems, and it is necessary to challenge and transform these systems in order to achieve gender equality and justice."

This statement reflects the core belief of feminist theory that gender is not a fixed biological category, but a socially constructed one that is shaped by cultural norms, institutions, and power relations.

Feminist theory aims to expose and challenge the ways in which gender norms and institutions, such as the family, the workplace, and the legal system, reinforce and perpetuate gender inequality, discrimination, and oppression.

Feminist theory also emphasizes the importance of centering the experiences, perspectives, and voices of marginalized and oppressed groups, particularly women, in order to understand and challenge the intersections of gender with other forms of oppression, such as race, class, sexuality, and ability.

in the united states and europe, what is the major recent change in love relationships?

Answers

The major recent change in love relationships in the United States and Europe is the rise of non-traditional relationships.

Specifically, there has been a significant increase in the acceptance and prevalence of same-sex relationships, as well as a rise in the number of people who are choosing to remain single or cohabit rather than marry.

Additionally, there has been a shift away from the traditional gender roles within relationships, with women now being more likely to pursue careers and men taking on more domestic responsibilities.

These changes reflect a broader trend towards greater individualism and personal choice in matters of love and relationships.

The rise of non-traditional relationships is a reflection of the changing values and attitudes of contemporary society. It reflects a greater emphasis on individualism and personal choice, as well as a more liberal and accepting attitude towards diversity in general.

The shift away from traditional gender roles is also reflective of a broader trend towards greater gender equality, with women now enjoying greater educational and employment opportunities and men being more willing to embrace domestic responsibilities.

While these changes have been met with resistance from some quarters, they are indicative of a broader shift towards a more open and inclusive society.

Answers

The Manson criteria, emphasized by courts, consist of five factors to be taken into account when evaluating eyewitness identification accuracy. According to the text, the  criterion that is the most problematic one is: "the level of confidence the witness is exhibiting about his or he memory of the event" (Option B)

What is the Manson Criteria?

The Manson parameters (view, attention, certainty, time, and description) were intended to clarify the concept that the ultimate problem is the reliability of the recognition, rather than suggestiveness in general.

When a witness identifies the individual who committed a crime, this is referred to as eyewitness identification. Witnesses identify criminals based on their physical view of the crime. Identification is not dependent on rumor or hearsay. An eyewitness is someone who observed the crime or has information about how it was committed.

Mistakes in identifying offenders can be impacted by a variety of variables, such as inadequate viewing conditions, insufficient time to watch the culprit or too much time between witnessing and identification. In laboratory investigations of eyewitness identifications, this process is mimicked.

stereotypes are supported and reinforced in a number of ways. which of the following is one of those ways? a) Prejudiced people fail to notice facts that support stereotypes | b) Prejudiced people can see no exceptions to the rule | c) Prejudiced people fail to recognize information that contradicts generalizations | d) Prejudiced people think they are not racis

Answers

Stereotypes are supported and reinforced in many ways. One of them is the way biased people fail to recognize information that contradicts generalizations. Here option C is the correct answer.

There are several ways in which stereotypes are supported and reinforced, and one of them is by the failure of prejudiced people to recognize information that contradicts generalizations. Stereotypes are generalized beliefs about a particular group of people that are often oversimplified and based on limited information, and they can be harmful when they are used to make assumptions about individuals based on their membership in a group.

When prejudiced people hold these beliefs, they may ignore information that contradicts their stereotypes and focus only on information that supports them. For example, if someone holds the stereotype that all members of a certain racial group are lazy, they may ignore evidence that contradicts this belief, such as a hardworking member of that group, and only focus on examples that support it.

This type of confirmation bias can reinforce stereotypes and make it difficult for people to challenge their beliefs. To combat this, it is important to actively seek out and consider information that challenges our assumptions and stereotypes, and to be open to revising our beliefs based on new evidence.

the symbolic representation of a particular attachment relationship is what bowlby called a(n) .

Answers

The correct option is internal working model. The symbolic representation of a particular attachment relationship is known as internal working model by Bowlby.

An early relationship a child has with their primary caregiver helps shape their internal working model of attachment. As the child develops, this mental image has an impact on how they interact and form relationships with others. It also explains how people behave differently from one another. According to psychiatrist John Bowlby's Theory of Attachment, young children are predisposed from birth to seek out their caregivers' company and proximity in order to survive, forming a strong attachment relationship. Children eventually internalise this attachment process and utilise these early ties as a model for later relationships with others outside of their immediate family. These archetypes of themselves and others make up this relational prototype, which is also known as the internal working models (IWMs).
