The owners of a coffee shop conducted a taste test to determine whether its customers preferred a new coffee brand to the current one sold by the shop. customers who were willing to participate were given small samples of each of the two brands in random order and were asked to select which one they preferred without knowing the brand. of the 100 participating customers, 90% chose the new brand. based on these results, the owners determined that a majority of their customers preferred the new brand and therefore switched their coffee supplier. stating that 90% of the taste testers preferred the new brand is an example of which type of statistics?

Descriptive Statistics

Step-by-step explanation:

There are mainly two types of Statistics:

1) Descriptive Statistics

Descriptive statistics provide simple summaries about the sample and the measures. When using descriptive statistics you are simply describing what the data shows.

2) Inferential Statistics

On the other hand, inferential statistics try to reach conclusions that extend beyond the immediate data alone.

In this case the decision made was based on the "90% of the taste testers preferred", and no more than that.  

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
