Which of the following statements about standard deviation is true?

A. Standard deviation is always a non-negative number.
B. Standard deviation is resistant to outliers.
C. Standard deviation measures the typical distance data points in a distribution are from the median.
D. Regardless of what units the data are in, standard deviation has no units.
E. If the data is measured in hours, standard deviation would be measured in hours squared.

Answers

Answer 1

Answer:

A. Standard deviation is always a non-negative number.

Explanation:

The true statement about standard deviation is that, standard deviation is always a non-negative number.

A standard deviation is calculated by taking the square root of variance and as such the value of standard deviation is always a positive number and not a negative number.

Additionally, the variance of a sample population is calculated by the summation of all the squared distances obtained from the mean divided by the total number of samples. Hence, all the values of the variance are always positive (non-negative) numbers because they are squared. Consequently, the standard deviation would as well always be a non-negative number.

Answer 2

The SD or the standard deviation is the measure of the amount of variation of the set of values. A low SD is close to the mean and a high SD indicates the values that are spread over a large region.

The SD has the same units as the variable. While the correlation coefficient is unitless. The SD is placed at an average distance from the mean value of all the variables.  If the standard deviation is in hours then the SD will be measured separately. Hence the option E is correct.

Dwight found a buried treasure with 4,023,743 pennies in it. (He counted twice to make sure.) Each penny weighs 3 grams. Dwight can carry up to 75 lbs. (even though he tells people he can carry much more). His 8 cousins can each carry 75 lbs as well. How many trips will he and his cousins need to make to carry all his money home?

Answers

Answer:

Number of trip = 39 trips (Approx)

Given:

Number of coins = 4,023,743 pennies

Weight of each coin = 3 grams

Each on carry weight = 75 lbs

Total number of people = 8 + 1 = 9

Find:

Number of trip

Computation:

Total weight of coin = 4,023,743 × 3

Total weight of coin = 12,071,229 gram

1 lbs = 453.529 gram

Total weight of coin = 12,071,229 / 453.529

Total weight of coin = 26,616.223 lbs

Total weight carry in each trip = Total number of people × Each on carry weight

Total weight carry in each trip = 9 × 75 lbs

Total weight carry in each trip = 675 lbs

Number of trip = 26,616.223 lbs / 675

Number of trip = 39.43

Number of trip = 39 trips (Approx)

'Energy' and 'power' are often confused, but aren't the same. Why do we say 'power plants' instead of energy plants'?

Answers

Answer:Both are important capabilities of a generator to keep the lights on.

Explanation:Power plants do provide both energy and power. Both are important capabilities of a generator to keep the lights on. And, in fact, power plants are rated, not by how much energy they produce, but by how much power they can produce, because if the grid does not have enough power generation capacity, it won’t work. It is arguably the more important parameter to specify in an electrical generation facility.

So, you could probably call them either power or energy plants. I do not know the history of why we chose to use power.

Where do you see cultural diversity in your everyday life?


please write 50-100 words

Answers

Answer:

We could quite safely state that in our society everybody

deals on a daily basis with people from different origins

and cultures. In our neighborhoods, places of work

and study, and even in our families, there are people

who come from different continents, who speak

different languages, practice their own customs and

profess different religions.

At the same time, we share and interact in the same

environment which has many common values and norms,

and we all act similarly in everyday events –like going to

school or work, going for a walk, playing sports, shopping

at the supermarket or watching television–.

Cultural diversity contains great potential for

educational and personal development as it allows

for mutual enrichment, thanks to those factors

that differentiate us –languages, customs, historic

memories, beliefs, etc.–. This mutual enrichment is

often made possible due to those factors that unit us

–common values and norms of coexistence in everyday

situations–.

We live in a plural society where cultural diversity exists

and is manifest on many levels: the autochthonous

population is diverse and the immigrant population is

made up of many sociologically and culturally different

groups. Although common aspects are shared, there

is also diversity within these groups as no person is

exactly the same as another. This diversity is manifest

in many different cultural expressions which form part

of human heritage
