1. A 35 steel specimens were subjected to a tensile load to obtain the yield strength. The standard deviation is 2.7 and sample mean is 250 MPa.

The 90% confidence interval for the yield strength of the steel is:

2 / 5

2. The moment of inertia about x' axis (mm^4) is:

3 / 5

3. A 1.5-kg ball is shot from the spring, which has a stiffness of 12 N/m. The spring is compressed 0.75 m by the plate with no load. After adding the ball, the spring compresses 1.25 m.

The velocity (m/s) of the ball when it reaches position 2.5 m:
