you are comparing the heights of contemporary males at 18th century males. the sample mean for a sample of 30 contemporary males is 70.1 in with a sample standard deviation of 2.52 in the sample mean for the 18th century males was 65.2 in with a sample standard deviation of 3.51 in is there sufficient data to conclude that contemporary males are taller than 18th century males​

a

step-by-step explanation:

answer: h

step-by-step explanation:

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.
