Explanation:

A) the is attached. Please see the picture

B)First to calculate the in its entirety mean,

μ=65∗25/75+80∗25/75+95∗25/75

μ=65∗25/75+80∗25/75+95∗25/75 = 80

Next to calculation E(MSTR) = σ2+(1/r−1) ∑ni(μi−μ)^2 = 5634

And E(MSE) = σ^2= 9

C)Yes, the is substantially big than E(MSE) in this case.

D)If us sampled 25 employee from every group, us are most likely to obtain a F statistics come indicate distinctions of project satisfactions among three types of length of service of employees.

Part A - transmitted power A solid circular rod is offered to transmit power from a motor to a machine. The diameter that the pole is

Explanation:

Given the solid circular rod rotates at consistent speed and neglecting losses throughout the system, power is calculated as the product that torque and also angular speed. That is to say:

*

There is a formula that relates torque through shear stress:

*

Where

*
is the torsion module, who formula for a hard circular cross section is:

*

The stress module is calculation herein:

*

Maximum enabled torsion is found by isolating that from shear stress and anxiety equation:

*

*

Then, maximum transmissible strength is determined directly:
