The student counts in these categories were Ž.Ž. 11, 52, 23, 22 when family income was low, 9, 44, 13, 10 when family Ž. income was middle, and 9, 41, 12, 27 when family income was high. a. Test independence of educational aspirations and family income usingX 2 orG 2 .Explain the deficiency of this test for these data. b. Find the standardized Pearson residuals. Do they suggest any association pattern? c. Conduct an alternative test that may be more powerful. Interpret.

my answer is$ 12

step-by-step explanation:

because 15 -2=12

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:

c > -10.55
