Apoll found that a particular group of people read an average of 12.8 books per year. the pollsters are 99% confident that the result from this poll is off by fewer than 3.93 books from the actual average x. express this situation as an inequality involving absolute value, and solve the inequality for x to determine the interval in which the average is likely to fall.

The interval in which the average is likely to fall :

Step-by-step explanation:

Given : A poll found that a particular group of people read an average of 12.8 books per year.

The pollsters are 99% confident that the result from this poll is off by fewer than 3.93 books from the actual average x.

The inequality to express this situation involving absolute value will be :-

Hence, the interval in which the average is likely to fall :

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.

step-by-step explanation:

11

32.50-7.50=25

225/25=11
