5. (10 points):
A credit card watchdog group claims that there is a difference in the mean
credit card debts of households in California and Illinois. The results of
a random survey of 250 households from each state are shown at the left.
two samples are independent. Assume that o = $1045 for California
and on = $1350 for Illinois. Do the results support the group's claim? Use
a = 0.05.

a is the correct

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.
