The los angeles times regularly reports the air quality index for various areas of southern california. a sample of air quality index values for pomona provided the following data: 30, 50, 40, 20 and 60 compute mean of the data compute the sample variance and standard deviation

Answers

Answer 1

The mean of the data is 40. The sample variance is 250. The sample standard deviation is approximately 15.81.

To compute the mean of the data, you add up all the values and divide by the total number of values. In this case, the data consists of the following air quality index values for Pomona: 30, 50, 40, 20, and 60.

Mean = (30 + 50 + 40 + 20 + 60) / 5

    = 200 / 5

    = 40

So, the mean of the data is 40.

To compute the sample variance, you need to calculate the squared differences between each value and the mean, sum them up, and divide by one less than the total number of values.

Variance = ((30 - 40)^2 + (50 - 40)^2 + (40 - 40)^2 + (20 - 40)^2 + (60 - 40)^2) / (5 - 1)

        = ((-10)^2 + (10)^2 + (0)^2 + (-20)^2 + (20)^2) / 4

        = (100 + 100 + 0 + 400 + 400) / 4

        = 1000 / 4

        = 250

So, the sample variance is 250.

To compute the sample standard deviation, you take the square root of the sample variance.

Standard Deviation = √(250)

                 = 15.81 (approximately)

Therefore, the sample standard deviation is approximately 15.81.

The issue of undocumented immigration in America is a topic of much debate. Some people believe that undocumented workers should be granted amnesty, while others believe that amnesty is not the right course of action.

Consider both sides of the amnesty issue and decide if you support or oppose amnesty.
In one paragraph, explain your position and defend your opinion with evidence in the form of details, examples, or statistics.

Answers

Answer:

below

Explanation:

To answer this question, we must first define "amnesty" to be based on something we can argue about. Amnesty, as defined by Merriam-Webster, is when a person or group in authority pardons a individual (or group of individuals) of a offense that they have done. The next thing we need to define is "undocumented workers". Undocumented Workers, as defined by WorkPlace Fairness, is not having met the requirements to be able to secure a citizenship or a permit, but is allowed to have working rights in the United States.

The question that is being asked here is whether or not illegal immigrants should be allowed to continue to work and live in a "legalized" status. In my opinion, they should not be allowed to be given amnesty. Remember, they are here for only to work, and if there is no other thing interfering with them being able to live inside their country (such as civil war, famine, persecution, etc.), they should continue to go through the same channel as others. Amnesty should only be granted to those who are in desperate need of it, and not to just anybody outside the country.

A subfield of philosophy known as "ethics" or "moral philosophy" aims to "systematize, defend, and recommend conceptions of right and bad action."
