high. The recession of the U.S. economy only hinders people more with high gas prices. A one population test using the One Factor ANOVA test and a five-step hypothesis test can be used to determine if gas prices are equally high in many different states. The samples used to test the hypothesis come from data collected from 30 randomly selected gas stations in six different cities. The hypothesis test and some solutions to consider may have an effect on direct and indirect stakeholders and is very important

Diagnostic and Statistical Manual Critique The Diagnostic and Statistical Manual of Mental Disorders (DSM) has a long history‚ starting back during World War II.

The T-Distribution and T-Test “In probability and statistics‚ Student ’s t-distribution (or simply the t-distribution) is a continuous probability distribution that arises when estimating the mean of a normally distributed population in situations where the sample size is small” (Narasimhan ‚ 1996). Similar to the normal distribution‚ the t-distribution is symmetric and bell-shaped‚ but has heavier tails‚ meaning that it is more likely to produce values far from its mean. This makes the t-distribution

3.1 Ex-vivo Evaluation of the Mucoadhesiveness of Synbiotics Mucoadhesive properties prolong the retention time of the bead’s dose in the targeted site the colon [23]‚ [50]. Since the dose is intended to colonic release‚ mucoadhesion parameters play a key role in the efficiency of the form. The beads remain longer in contact with colonic mucosa when they have more mucoadhesive property. As a result the probiotics will have enough time to get released from beads and colonize the colon [37]‚ [51]

to research the validity of standardized tests in school. The standardized tests can include the Stanford 9‚ PSAT‚ SAT‚ CRCT‚ etc. I chose this topic because I feel that educators and political leaders place an undue amount of importance on it. A flaw in standardized testing is that while two students know the same subject material‚ one may get a question right while the other does not. Through my research‚ I tried find a more effective personalized test that would help most of the students. This

the power of the tests that have appeared in the literature as well as tests motivated by the work of Larkey‚ Smith‚ and Kadane (LSK). Three test statistics for the null hypothesis of Bernoulli trials have been considered in the literature; one of these‚ the runs test‚ is effective at detecting one-step autocorrelation‚ but poor at detecting nonstationariy. A second test is essentially equivalent to the runs test‚ and the third is shown to be worthless. The LSK-motivated tests are shown to
