    1) How might you use the strategies for applying creativity to problems and issues in addressing this topic? In the article that I wrote about it discusses the issue of how Essex County Executive, Joe DiVincenzo, was using his campaign funds to pay for personal expenses. According to the article the laws concerning this matter requires disclosure of all expenses, including those incurred on a credit card. It also states that from 2002 to 2011 DiVincenzo had approximately $250,000 charged to his personal credit card, which was paid with the campaign account, but never gave any explanation as to what the charges were for. The strategy for applying creativity that would best be used for this issue would be to devise or modify a process or system. Apparently, the laws that are in place for this matter are not specific enough, and there is a lack of enforcement. These laws need to be modified to make their…

    In this section, we describe how to perform hypothesis tests and construct confidence intervals for the standard deviation of a normally distributed variable. Such inferences are based on a distribution called the chi-square distribution. Chi is a Greek letter whose lowercase form is χ. A variable has a chi-square distribution if its distribution has the shape of a special type of right-skewed curve, called a chi-square (χ2) curve. Actually, there are infinitely many chi-square distributions, and we identify the chi-square distribution (and χ2-curve) in question by its number of degrees of freedom. Basic Properties of χ2-Curves are:…

    Although there are a number of methods of estimating the standard deviation of a population the sample standard deviation is the most widely used estimator of this parameter. If we use s to make inferences about ( (or s2 to make inference about ( 2 ) the theory on which a confidence interval for ( is based requires that the population sampled has roughly the shape of a normal distribution, in which case the statistic called (2 has as its sampling distribution an important continuous distribution called the chi square distribution [pic] .
