In a condominium (commonly called a condo), some parts of it, like our residence - are owned privately, while others - common areas - are owned collectively by all of the building's residents. A less technical way of describing a condo is an apartment that you own. In real-world terms, condos often take the form of an apartment or similar

Introduction In-Process Technology was set up in 1985 to produce and sell a thermal oxidation process that could be used to reduce industrial pollution. For years, however, the company performed dismally. In 1992, the current CEO was hired to turn things around, and the company was reorganized and renamed Thermatrix. Eventually, Thermatrix was able to attract good employees using stock options and other competitive compensation and currently has 60 employees and annual sales of approximately $15

477 A) Construct a 90% confidence interval for the true mean weight Assuming the population has a normal distribution, we should use the Student t distribution E= z(sigma)/ sqrt(n) E= 1.645(0.13199/ sqrt(10) E= 0.06866 x-bar= 3.3048 90% CI = 3.3048-.06866= 3.23614, 3.3048 + 0.06866 = 3.37346 Confidence interval: 3.23614 to 3.37346 B) What sample size would be necessary to estimate the true weight with an error of +,- 0.03 grams with 90% confidence ? E = z*sigma/sqrt(n)

The Journey to Finding Confidence The walk home from school during my elementary years was something I loved. Not only did I look forward to it because it meant that school was over for the day, I also looked forward to it because it was one of the few times I had to myself. Amidst the chaos of little kids laughing, screaming, and racing each other home, I would tune out the noise and just think. Eventually I would make it home; my time alone would expire, and I would find myself looking forward

Statistics Practical 2a Comments on Z-tests and t-tests 1. You should have realized from the lectures that in practice, a z-test is seldom used, while the ‘default’ test for single sample or two-samples mean(s) is the ttest. This is because in most practical situations, the population variance is seldom known and therefore we need to estimate that by the sample variance, thus justifying a t-test rather than a z-test. It is always good to perform the standard exploratory data analysis before commencing
