Statistical hypothesis testing

BACKGROUND (CASE STUDY WRITE UP) Quality Associates, Inc. is a consulting firm who advises its clients about statistical and sampling methods that can be used to control their manufacturing procedures. In this particular case we consider a production line designed to fill bottles of a shampoo with a mean weight of 12 ounces of shampoo per bottle. Quality Associates, Inc. made a quality control testing of the manufacturing machine of this client (Alibaba Machinery), to determine if the process is operating

Terrorism Experience is an independent variable representing the depth of proficiency, knowledge, best practices and insights that corporations, who were directly impacted by a specific terrorist incident, acquire from coping with the effects of terrorism. The Terrorism Experience is measured in terms of the cumulative number of terrorism incidents that directly affected the firm. The number of attack incidents on a firm is a Traditional type of terrorism measurement as categorized by Frey et al

the remaining four crickets. A Chi-square test was used for hypothesis testing. This is used to determine that the observed number of wins of the resident from the trials is different from what would be observed by chance. The null hypothesis was observed wins will be equal to that expected by chance. On the other hand, the alternative hypothesis was observed wins will not be equal to that expected by chance. The class’ hypothesis was proven correct that resident male crickets have a greater motivation

was hypothesized that as the concentration of substrates increases, the reaction rate will as well. The null hypothesis for this is that the substrate concentration will have no effect on the reaction rate. For the varying temperature of catalase, it was hypothesized that as the temperature increases, the reaction rate will increase as well until the enzyme is denatured. The null hypothesis for this is that varying temperature will have no effect on the reaction rate. The experiment was completed

In the earlier post about bioequivalence, I briefly mentioned the formulation of hypotheses for testing bioequivalence. The null hypothesis states "Bio-inequivalence", while the alternative states "Bioequivalence", as formulation (I). H0: bio-inequivalence; Ha: bioequivalence (I) One might argue that the null and alternative hypotheses are incorrectly reversed, since what we generally do is to put statements like "no difference", "no effect", "equivalent", or "equal to 175 lbs" as

The theme of transfer of learning was woven within three articles. The first article was “Effects of frequency of feedback on transfer in concept identification” by Marvin L. Schroth. The second article was “Schema Induction and Analogical Transfer” by Mary L. Gick and Keith J. Holoyoak. The third article was “The Equivalence of Learning Paths in Early Science Instruction: Effects of Direct Instruction and Discovery Learning” by David Klahr and Milena Nigam. “Effects of frequency of feedback on transfer

Background Information: The study took place in north Europe Scandinavian countries such as Denmark, Norway and Sweden. The local paediatrician from Norway and Sweden and the forensic institution of Denmark invited parents of sudden infant death syndromes (SIDS) to take part in the study. Sudden infant death syndrome is the sudden, unexpected and unexplained death of an apparently healthy baby. There were several aims behind the study. The main aim of the study was to overlook whether smoking was
