A scientist has a hypothesis that as the number of police cars is increased on a roadway, the proportion of cars speeding decrea
ses. He finds that at police car level X1 (one police car per 100 miles), the proportion of cars speeding is p hat equals 0.83. At police car level X2 (one police car per 50 miles), the proportion of cars speeding is p hat equals 0.61. At police car level X3 (one police car per 25 miles), the proportion of cars speeding is p hat equals 0.39. Should the hypothesis be rejected or should it fail to be rejected?
<span>yes the cars has been shrunk and are not able to reject because the could just stand up and walk of without rejecting unless they are in a helicopter they have to find a landing spot to do so and if they are in a train they need to pull the brakes if the brakes dont work the have to jump out and roll in rocks or grass and if they are</span>
If a number is getting subtracted by a negative number the minus sign and the negative sign cancel eachother and become a positive sign that's why there's 2 plus signs because they became positive
