Explain why we must verify whether or not the assumptions of an inferential statistical test are met before we calculate the statistic. Specifically, what does a failure to meet the assumptions mean in terms of the α level of our experiment? What should we do if the assumptions are not met?

4. An experiment involves randomly picking a single ball from an urn and recording the color. The urn contains 19 balls, three of the balls are red, ten of the balls are green, and the rest are blue.

1. Find the probability that the ball is blue or green.

2. Find the probability that the ball is blue given that it is not red.

In a Compton scattering experiment, an x-ray photon scatters through an angle of 22.2° from a free electron that is initially at rest. The electron recoils with a speed of 2,520 km/s.

(a) Calculate the wavelength of the incident photon.
nm

(b) Calculate the angle through which the electron scatters.

What is the solubility of AgCl om 0.01 M AgNO3? What and how large is the error this solubility would cause in the results of gravimetric experiment? you may assume the total volume of the solution to be 250 mL. Please comment on the significance of this amount of chloride lost due to solubility.

2. In a Compton scattering experiment, an x-ray photon scatters through an angle of 21.4° from a free electron that is initially at rest. The electron recoils with a speed of 1,880 km/s.

(a) Calculate the wavelength of the incident photon.

(b) Calculate the angle through which the electron scatters.

When cells migrate, they exert forces on substrate surfaces. Design an experiment to study the magnitude of the forces.Please provide detailed description for each step. (Hint: label the surface, detect surface deformation, reference: Kong H J et al. PNAS 102:4300 (2005))

1. (a) List the sample space in the experiment "roll two dice - a red die and a white die." (Hint: Use a table)

(b) Find the probability that the sum of the numbers on the two dice is less than seven.

(c) Find the probability that the sum of the numbers on the two dice is odd.

I want to build a thin flexible rubber sheet, embedded with piezoelectric materials to convert mechanical energy into electrical energy.

Can anyone please tell me how i can proceed with this experiment?

or if there is any online supplier where i can buy from?
