question in a controlled (practice) setting. A large simulation study examines 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

Null Hypothesis H0: There exists a relationship between percentage money spent on gdp and the infant mortality rate. Alternate Hypothesis H1: There is no relation between percentage money spent on gdp and the infant mortality rate Independent Variable – Percentage of GDP spent on education Dependent Variable – Infant

This paper outlines the sampling and data collection procedure used to test the null hypothesis. The null and alternate hypotheses are: (There is no significant difference in brand awareness based on the marketing channel used).

included questions covering the whole four weeks. As for statistically analyzing of the exam results‚ the Null Hypothesis was laid down. The latter stated that “There is no statistically difference between the control and the experimental group due to the assessment rich PBL approach”. The statistical analysis of the exam results showed very strong statistical evidence to reject the Null Hypothesis. The experimental group students outperformed significantly the control group students. The results showed

The Null hypothesis of this study is that the mean for each variable is equal to that of the other variable. The alternate hypothesis to this study is that the mean of group one and three are not equal to the mean of group one. The effect size used F test for its three groups.
