The Mann-Whitney U test is often considered the nonparametric alternative to the independent t-test although this is not always the case.

Lim x--> 0 (e^x(sinx)(tax))/x^2

Tom [10]

Make use of the known limit,

$\displaystyle\lim_{x\to0}\frac{\sin x}x=1$

We have

$\displaystyle\lim_{x\to0}\frac{e^x\sin x\tan x}{x^2}=\left(\lim_{x\to0}\frac{e^x}{\cos x}\right)\left(\lim_{x\to0}\frac{\sin^2x}{x^2}\right)$

since $\tan x=\dfrac{\sin x}{\cos x}$ , and the limit of a product is the same as the product of limits.

$\dfrac{e^x}{\cos x}$ is continuous at $x=0$ , and $\dfrac{e^0}{\cos 0}=1$ . The remaining limit is also 1, since

$\displaystyle\lim_{x\to0}\frac{\sin^2x}{x^2}=\left(\lim_{x\to0}\frac{\sin x}x\right)^2=1^2=1$

so the overall limit is 1.

Percent decrease=decrease/original times 100

decreas=860-790=70
original=860

percent decrease=70/860 times 100
percent decrease=0.0813953 times 100
percent decrease=8.13953
about 8%

In your own words, describe the difference between correlation and causation. Give an example (not given in the content) of two

Semmy [17]

The difference between causation and correlation is that, Causation is characterized by cause-and-effect while correlation establishes a probable relationship.

<h3>What is the difference between Causation and correlation?</h3>

While Causation is characterized by a situation in which an action certainly causes an outcome and hence, is described as a cause-and-effect relationship, Correlation on the other hand only establishes a relationship between the two events and doesn't necessarily ascertain the occurrence of the other event .

An example of two variables which may be correlated is; the height and weight of an individual in which case it is generally perceived that taller people are heavier.
