1. Eighty-nine percent of Americans polled are in favor of arts education being taught in public schools.

a. Does the above numerical value describe a parameter or a statistic?

b. After reading the above statement, you decide to campaign for the arts in education and

use the statement: "A majority of Americans are in favor of art education, which shows

their love of arts. Americans support ballet teaching in public schools." What branch of

statistics would you be applying?

a. parameter

b. descriptive statistics

Step-by-step explanation:

The values of the population charactersitics are summarized by certain numerical descriptive measures called parameters.

The observations composing a sample are used to calculate a corresponding numerical descriptive measure called a statistic.

a. The percent of Americans is of a population and therefore it is a parameter not a statistics.

b. Descriptive statistics deals with the collection, summarization and display of data.

Inferential statistics deals with conclusions drawn based on a sample.

This is descriptive statistics because it is displaying of data collected from a population of America.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

you can't solve x because it is 2 linear equation and you only have one equation
