where the falling of bottles is produced. The simulation was used to evaluate different scenarios where the worker allocation gets the best impact in terms of reduction of failures‚ which results in a higher rate of production. The paper presents a statistical analysis to validate the simulation model as well as the use of Bonferroni’s [1] approach to compare several scenarios. The main conclusion is that by reducing the failures in the washing process area significant increase of the production is obtained

Sample 9.23 A manufacturer of chocolate candies uses machines to package candies as they move along a filling line. Although the packages are labeled as 8 ounces‚ the company wants the packages to contain a mean of 8.17 ounces so that virtually none of the packages contain less than 8 ounces. A sample of 50 packages is selected periodically‚ and the packaging process is stopped if there is evidence that the mean amount packaged is different from 8.17 ounces. Suppose that in a particular of 50 packages

Provide a rationale for your answer. “A Type I error is defined as rejecting a true null hypothesis (not being a believer in the utility of testing point null hypotheses‚ what I really mean here is rejecting a null hypothesis that is so close to true that for practical purposes it is true)” (Wuensch‚ 1994). No there is not a type I error in this study. The two groups are significantly different.

The hypothesis is a claim that needs to be investigated. In our case we are investigating if our bottles contain less than sixteen ounces of water. First we look at the NULL hypothesis‚ this is the established value that we accept to use as our parameter. (Ho) We know that sixteen ounces is our accepted parameter. Next we look at the alternative hypothesis. The alternative hypothesis is the claim being tested. (Ha) We start by knowing that there

Chapter 1: The Problem and Its Background Introduction Carinderia is a local eatery selling and serving affordable viands for the masses. It is also known as “turo-turo” wherein customers literally point what they want to eat. Carinderia is most likely derived from the word “cari” or “kari”‚ a Tamil word for sauce‚ or a saucy accompaniment for rice.
