URGENT Economists often track employment trends by measuring the proportion of people who are "underemployed,"
meaning they are either unemployed or would like to work full time but are only working part-time. In the
summer of 2010, 18.5% of Americans were “underemployed.” The mayor of Springfield wants to show the voters
that the situation is not as bad in his town as it is in the rest of the country. His staff takes a simple random sample
of 300 Springfield residents and finds that 48 of them are underemployed.

(a) Do the data provide convincing evidence that the proportion of underemployed in Springfield is lower than
elsewhere in the country?

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:
