Which of the following is NOT a possible value for the correlation coefficient? 1) negative 0.9 2) zero 3) positive 0.15 4) posi

AnnyKZ [126]

Answer:

4) positive 1.05

Step-by-step explanation:

Correlation:-

Correlation is a statistical measure that indicates the extent to which two or more variables fluctuate together.

Examples:i) The yield of a crop varies with the amount of rainfall

ii) The price of a commodity increases with the reduction in its supply and so on.

That is when the changes in one variable are associated or followed by changes in the other, is called correlation

positive correlation:- If an increase (or decrease ) in the values of one variable corresponds to an increase(or decrease ) in the other, then correlation is said to be positive.

negative correlation:- If an increase (or decrease ) in the values of one variable corresponds to an decrease(or increase ) in the other, then correlation is said to be negative.

no correlation:-

If there is no relationship indicated between the variables,they are said to be independent or uncorrelated.

uses of correlation:-it is used in presenting the average relationship between any two variables through a single value of co-efficient of correlation. correlation is a statistical technique that can show whether and how strongly pairs of variables are related.

The range of correlation is $-1\leq r\leq 1$

r=-1 is the negative correlation

r=1 is the positive correlation

so the answer is not a possible value for the correlation coefficient is positive 1.05.

In which two locations do tropHarry just got a new job that requires him to transfer from a tropical climate to a continental cl

pshichka [43]

Answer:

B. a warm coat, because the winters will be cold

Step-by-step explanation:

Continental climates are notable for extreme weather conditions. When it is hot, it is extremely hot and when it is cold, it is extremely cold. Tropical climates on the other hand are known to always have hot weather conditions.

Since Harry is already used to the tropical climate which largely features hot temperatures, we assume that he already has suitable clothing for such weather conditions. So, in addition to that, Harry would need warm clothing for the cold winters which he would experience in the continental climate. So, Harry would need a warm coat because the winter will be cold.
