A manager is asked to condense a set of two hundred and forty nine personal income figures into a meaningful set of charts and graphs. What type of statisitical problem is the manager dealing with? statistical inference, probability, descriptive statistics, statisitical sampling, the situation described is not a statisitical problem.

Problem 8 Trc) A silicon wafer is doped by Phosphorous via Diffusion at 1090C. 12:00 1000 Assume the measured Phosphorous profile can be represented by a Cu Gaussian function. The solid solubility of phosphorous is 1017 cm", 10 and the measured junction depth is 1 um at a substrate LI concentration of 1016 cm 3. Calculate the diffusion time and the total Au Na dopant in the diffused layer.

This occurs when the electromagnetic radiation's transverse electric and magnetic fields are described by a Gaussian function.
