Imagine that a researcher wants to study the proportion of new diabetes diagnoses from year to year. She suspects that a greater percentage of people were diagnosed with diabetes this year compared to last year. She has complete data on diabetes diagnoses from last year. Determine the hypothesis test this researcher should use. Select from the list below.

A. one-sample, left-sided -test for a proportion

B. one-sample, right-sided -test for a proportion

C. one-sample, -confidence interval for a mean

D. one-sample, left-sided -test for a mean

E. one-sample, right-sided -test for a mean

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.
