The standard normal variable is z
z=xμσ
When x=79,z=1.8i.e.
1.8=79μσμ+1.8σ=78
When x=64,z=0.8i.e.
0.8=64μσμ+0.8σ=64
Solving the above two equations give
σ=14
Now, μ+1.8(14)=78μ=52.8
When x=52
z=5252.814=0.06
When z=1.4
1.4=x52.814

⇒=33.2
Answer: μ=52.8 and σ=14

For tests using a ballistocardiograph, a patient lies on a horizontal platform that is supported on jets of air. Because of the air jets, the friction impeding the horizontal motion of the platform is negligible. Each time the heart beats, blood is pushed out of the heart in a direction that is nearly parallel to the platform. Since momentum must be conserved, the body and the platform recoil, and this recoil can be detected to provide information about the heart. For each beat, suppose that 0.050 kg of blood is pushed out of the heart with a velocity of +0.30 m/s and that the mass of the patient and the platform is 85 kg. Assuming that the patient does not slip with respect to the platform, and that the patient and the platform start from rest, determine the recoil velocity.

When a person stands on tiptoe (a strenuous position), the position of the foot is as shown in Figure (a). The total gravitational force on the body, vector F g, is supported by the force vector n exerted by the floor on the toes of one foot. A mechanical model of the situation is shown in Figure (b), where vector T is the force exerted by the Achilles tendon on the foot and vector R is the force exerted by the tibia on the foot. Find the values of vector T , vector R , and θ when vector F g = 805 N. (Do not assume that vector R is parallel to vector T .)

ABC Company manufactures purple widgets. The company has established a total standard cost for direct material and direct labor of $244.33 per widget. The total standard cost includes 21.5 pounds of direct materials at a standard cost of $10.50 per pound and 3.45 hours of direct labor at a wage rate of $8.50 per hour. The following data pertain to April:
The company purchased 500,000 pounds of material, 90% of the material purchased was used for direct materials.
The total cost of the direct materials was $4,050,000.
The total amount paid for direct labor was $600,750.
The actual direct labor hours worked was 67,500 hours.
The company actually produced 20,000 widgets for the month of April
