Which of these variables is least likely to have a normal distribution? a. annual income for all 150 employees at a local high school b. lengths of 50 newly hatched pythons c. heights of 100 white pine trees in a forest d. amount of soda in 60 cups filled by an automated machine at a fast-food restaurant e. weights of 200 of the same candy bar in a shipment to a local supermarket?

Annual income for all 150 employees at a local high school

Step-by-step explanation:

The normal distribution is also called the Gaussian distribution. It is the most common type of distribution for statistical analysis. The normal distribution is based on a probability distribution. The data near the mean are more frequent than the data away from the mean. It is based on two parameters: the mean and the standard deviation.

As per options, option A which states ‘annual income for all 150 employees at a local high school’ the data is within the standard deviation.  

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
