A manager has hired a consultant to compare two ways a product is presented to customers. Twelve customers are presented with each product. What would be the roles of descriptive and inferential statistics in the analysis of these data

The role of descriptive statistics in data analysis is to provide descriptions of the population characteristics, using numerical calculations, graphs, and tables.  Descriptive statistics describe what is going on in a population or data set.

On the other hand, inferential statistics make predictions and draw inferences about a population using the population sample.

Step-by-step explanation:

The two types of statistics are descriptive statistics and inferential statistics.  Descriptive statistics describe sets of data, allowing patterns to emerge from the data.  These also enable the presentation of the data in a more meaningful way, allowing for simpler interpretation of the data. Two types of descriptive statistics help in this regard.  They are measures of central tendencies and measures of spread.  Inferential statistics draws conclusions about the sets of data based on sampling, allowing for the making of generalizations and testing of hypotheses.

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
