GGR270H1 Final: Week 1 Study Notes

Assume that there are about  peoples and   householders in dire dawa city. A statistician who conducted a statistical analysis about the size family size and monthly income of dire dawa households collected data only from  households. The found that the average following questions from.

A).If a statistician describes the collected data and uses the result only for dire dawa households, then the statistical approach used is possible?

B). If the statistical used this result to generalize for the households in adis abeba or adama or mekele, then the statistical approach used is possibly?

C). Write the step or stage a statician will probably follow to conduct the above statistical study? 

How would the position of Fermi level EF with respect to the intrinsic energy level Ei change, if instead of Boltzmann statistics, Fermi-Dirac statistics were used?

When determining the acceleration over a time, thefollowingstatistics are provided:
Average: 0.107
Standard Deviation: 0.120
Number of points: 54

Write the value and its uncertainty in appropriate form.
