The right answer is b

The hypothesis test that is best suited to determine the proportion of smokers in Idaho is One Proportion Test.

One Proportion Test is a hypothesis test that is used to estimate a proportion and facilitate comparison with another proportion.

One Proportion Test works by comparing the proportion to the  target/reference value.

Here, the One Proportion Test will help to compare the Idaho current samples to statistics of smoker collected in 2014.

Therefore, the Option E is correct because it is best suited to determine the proportion of smokers in Idaho is One Proportion Test.

The missing options includes "One mean, Mean of the differences, Difference of two means (independent samples), Several means (ANOVA), One proportion, Difference of two proportions, Chi-Square test of independence"

Answer:

The Hypothesis test to use is the Test for Proportions.

Explanation:

There are quite a number of test to select form when analysing a statistical data. Selecting the right one can be quite tricky. When deciding which test you ought to use, there are three questions you need to answer:

1. Data (What level of measurement was used for the data being analysed?)
2. Samples (How many samples do we have?)
3. What is the purpose of the analysis?

Data

The type of data we are presented with is captured in in percentages. This is an example Nominal data.   Nominal summary values are usually stated as frequencies, proportions or percentages.

The tests that involve nominal data are:

1. Test for a proportion;
2. Difference of Two Proportions and
3. Chi Square test for independence

From the criteria above, it's clear we are dealing with Difference of Two Proportions.

Samples

This criteria begs the question: How many samples are involved?

1. Is it one sample for whose statistic (s) is being compared with a hypothetical value? or
2. Are there two sample being which are being compared with each other?
3. Is there one sample in which there is a measure or score for more than one variable? e.g. colour and grade or circumference and weight.    

From the criteria above, it's clear we have One Sample with two different considerations - Smoker or Non-smoker.

Purpose

1. Are we testing against a hypothesized value?
2. Are we comparing two statistics? or
3. Are we looking for a relationship?

You are right! From the example above, we are comparing two statistics.

Therefore putting all the criteria together, we ought to use Test for Proportions is best suited for this situation.

Cheers!

Toinvolve students in community work and develop a sense of social responsibility, the school could develop three strategies:

1- Create a social responsibility fair, with scavenger hunts, lectures, shows and events worth extra points for teams that develop more innovative ideas on the topic.

2-Promote excursions to social institutions such as nursing homes and support houses for drug addicts, for students to broaden their perception of the needs and experiences of people who go through certain difficulties, increasing their sense of community and responsibility.

3- Carry out essay competitions on social responsibility and how students can contribute to the development of society.

Social responsibility is the ethical sense of individual and collective contribution to make a society more egalitarian for all individuals, with small daily actions we are able to positively impact the society in which we live.

• Email your students to remind them that you are still there for them.

• Tell them how you are shifting your schedule to deal with the new situation and that change is part of life. Humanize yourself and make it casual and lighthearted. For example, you might talk about how, in between reading their discussion posts, you decided to start your spring cleaning, which you’ve been putting off forever.

• Reflect on the notion of rigor and continue to challenge and support your students. As instructors, we often must balance rigor and support, and this situation might be one where students will need more support than rigor. Establishing continuity doesn’t mean you increase the amount of work required of them. I say this because I worry that some of us might be fixated on the rigor of the materials presented. Let’s face it -- the rigor may suffer, and that’s OK considering the situation.

• Repeat some of the lessons you taught in class. Especially for those students who are missing the classroom environment, this will probably help activate their memory of being part of a community and remind them that they are still part of one. For example, in your email you can say something like, “Remember when we talked about this and …”

Use hopeful and optimistic language, such as, “When you come back this fall …” This will help students look forward to coming back to the campus.

Answer: Specialization reduces the cost of production.

Explanation:

Specialization is a method of production where an employee simply focuses on one particular aspect of production or a particular area or department in order to gain more efficiency.

It should be noted that specialization increase productivity as the workers will be more effective and efficient thereby leading to the reduction in the cost of production which will invariably lead to increase in production as there'll be more resources to aid production.

They help to ensure the environment is optimally used well and profitable for everyone, especially with sustainable actions.

Society is everyone's responsibility. Humans are the society and for society to be maintained or sustained, everyone has to do their bit by carrying out actions to the benefit of themselves and others.

A case study is keeping the society clean, if everyone dumps trash anyhow, it's to the detriment of not just the environment but also the health of everyone, if it's otherwise, the health of everyone is preserved. This shows that everyone has a responsibility of keeping the society clean.

Another area is theft, if everyone is willing to work, no matter the kind of job, there won't be theft in the society, but we have theft due to some individuals greed and laziness.

With this scenario, you would realize that we all have a responsibility to handle our society well, and our actions are result in the lives of others.
