Use of CrunchIt is required for this question. Round answers to four decimal places. One report states that 51% of American adults have life insurance. Use this information to completely describe the sampling distribution of the sample proportion of American adults that have life insurance for a sample size of 120 adults. shape: [a1] mean = [a2] standard deviation = [a3] What is the probability that in sample of 120 American adults the proportion that have life insurances is more than 52%? [b]  

A 2000 Kg truck is being used to lift a 400 Kg boulder B this on a 50 Kg pallet A. Knowing that the acceleration of the rear wheel drive truck is 1m/s^2 to the left. The center of gravity of the truck is shown with a black dot, which is 1m above the ground and 1.4m to the right of the leftmost wheel. The cable attached 0.6m above the ground. All of this is shown in the problem Determine (a) The acceleration of the boulder and pallet  (b) The reaction at each of the front wheels Hint:   Because the truck is rear wheel drive there can be a horizontal force at the rear wheel (the wheel farthest right). This force is due to friction between the wheel and the road. The front wheel only has a vertical reaction force. Ex) Your answer may be something like      Front Wheel (leftmost):   50N upwards                                                                                                                                        Rear Wheel (right wheel):   100N upwards and 30N to the right (c) The force the boulder (B) feels from the pallet (A) 

Which of the following are part of the bimanual examination?

Determine whether each statement is true of false and explain why 1) The sum of force vectors on an airplane moving with constant velocity is not zero 2) A satellite in a circular orbit with a constant speed of 10km/s is accelerating 3) If an object is not accelerating the sum of the moment vectors is zero, but only about a point on the body
