Answer:

The correct answer is 3) Most of the data points are close to the mean value of the set.

Explanation:

This is an informal approach. However, to test for the normality of a distribution, you want to ensure that you compare a histogram of the sample data to a normal probability curve.

If the empirical distribution of the data is bell-shaped then it is normal. Of course, this alignment may be difficult to see if the sample data is too small.

It is important to look out for normality because, in statistics, normality tests are required to establish if a data set is properly modeled by a normal distribution and to calculate the probability for a random variable within the data set to be normally distributed.

Cheers!

estamos construyendo una carretera que enlace los puntos a = 12 ,21 y b =(17,23) otro punto se encuentra en c =(3,9) es posible

Answer:

is not possible

Step-by-step explanation:

The question in English is

we are building a road that links the points a = (12 ,21) and b =(17,23) another point is in c =(3,9) it is possible that a single road allows to join these three points?

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$
