The answer is c; the absolute value of -13 is 13, as the absolute power is the distance between the number and 0

Answer:

I would say B

Step-by-step explanation:

when you are going down you tend to go faster because of gravity. So you would go down, up, down, up, and a little down. This would make B the answer because the speed is increasing when it goes down so that is the only answer that would make sense. Hope this helped! Have a good day! :)

A local school board member randomly sampled private and public high school teachers in his district to compare the proportions

levacccp [35]

Answer:

0.025 ;

(-0.7198 ; 0.7698)

Step-by-step explanation:

From the table :

_____________ private schls ___ public schls

Sample size, n _____ 80 __________ 520

P, NBC teachers ___ 0.175 ________ 0.150

P1 = P of private school teachers

P2 = P of public school teachers

Difference in proportion :

P1 - P12 = 0.175 - 0.150.= 0.025

The 90% confidence interval for 2 - sample proportion :

C.I = (p1-p2) ± [Zcritical * √(p1(1-p1)/n1 + (p2(1-p2)/n2)]

Zcritical at 90% = 1.645

C.I = 0.025 ± [1.645 * √((0.175*0.825)/80 + (0.150*0.850)/520)]

C.I = 0.025 ± [1.645 * √(0.0018046875 + 0.0002451)]

C.I = 0.025 ± 1.645 * 0.0452755

C.I = 0.025 ± 0.07448

C.I = (-0.7198 ; 0.7698)
