1. Why is the state fake a concern when estimating a c alone back? * If the world shape is symmetrical, it will be a concern when estimating the inculpate. The distribution would be close to the center. It all depends on how thin the mean is, for example when it is very sensitive in the perfect values and the distribution is non symmetrical, and the mean will be away from the center and more advance the extreme values. In statistics normality is important so the profound community is normally distributed. (Doane & Seward, 2007) * What effect does exemplification size, n, puzzle on the estimate of the mean? Is it possible to normalize the information when the population shape has a known skew? How would you edge the primal desexualize theorem to your classmates? * When the sample size is large the small the type deviation or error, then you will take up a more dependable estimate. Also remember to give way the mean with bigger samples. Base d on the normality, the central limit theorem is relied on all statistics and tests. It is possible to normalize the data when the population shape has a known skew. There are galore(postnominal) ways for normalizing skewed distribution, for instance using the square free radical break and logarithmic transformation just to name a few.

(Sekaran, 2003) starting signal with a instal of data which is not standard, any non-normal or probably the uniform distribution would model in explaining it emend to other students. * Example 1; here(predicate) is an example of how a not so normal histogram abstract (Histograms, 2012) * * The choice of choosing samples f! rom the set of data of size 6, calculates the mean, then plagiarize several measure more, then change to a larger sample size. When your sample sizes increases you will see the histogram of the mean smelling like a normal distribution. When you have added target, upper and turn away limit lines, you potty examine your histogram to see how your process is performing. (Histograms, 2012) * 2.
