can be applied to a relatively small number of cases. It was specifically designed to evaluate statistical differences for samples of 30 or less. 2.0 DEFINITION OF T-TEST A t-Test is any statistical hypothesis test in which the test statistics follows a Student’s t distribution if the null hypothesis is supported. 3.0 A BRIEF EXPLANATION One of the most commonly used statistical procedures is the t-test. There are actually three variations of the t-test that we will consider. These are the single-sample

From this case‚ there are two types of errors‚ which the consortium can make. A Type I Error is referred to as a “false positive.” A Type I error would be made when the null hypothesis is rejected when it should be accepted. This error may occur if the consortium defends any lawsuit against them if they are using 6% (6/100) as their surveying result. The results of the sample size of 100 people indicate that the percentage range is from 1.35% to 10.65%. The test results can be higher than 10%‚ but

CHAPTER I The Problem and Its Background Introduction Education is instrumental in harnessing man’s potentials and capacities to make him a productive and effective member of society; hence the total development of the individual is the ultimate aim of education. Thus‚ schools were established in all feasible areas to quench man’s quest for further knowledge and optimum development. In effect‚ awareness to the significant benefits of education directed the school towards offering different courses

the logic of a hypothesis test? “If our sample result is very unlikely under the assumption of the null hypothesis‚ then the null hypothesis assumption is probably false. Thus‚ we reject the null hypothesis and infer the alternative hypothesis.” • What is the logic of using a CI to do a HT? We are 95% confident the proportion is in this interval… if the sample mean or proportion is in the confidence interval the null hypothesis could be inferred. Else‚ the alternative hypothesis would. •

Introduction Exchange rates play a vital role in a county’s level of trade‚ which is critical to every free market economies in the world. Besides‚ exchange rates are source of profit in forex market. For this reasons they are among the most watched‚ analyzed and governmentally manipulated economic measures. Therefore‚ it would be interesting to explore the factors of exchange rate volatility. This paper examines possible relationship between EUR/AMD and GBP/AMD exchange rates. For analyzing relationship

regression is to determine if there is a correlation between the poverty rates and literacy rates in different states within USA. My null and alternate hypothesis are as follows: Null hypothesis: Ho: β1 = 0 This hypothesis states that there is no correlation between the literacy and poverty rates Alternate hypothesis: Ha: β1≠0 This is the hypothesis we want to prove‚ there is correlation between the literacy rate and poverty rates The first step I did was to create a scatter plot for the data and

times of the standard deviation. This can be best expressed as in the equation of 2s = 2(12.28455) which equals 24.57 average hours per week. Then‚ we can analyze the accuracy of hypothesis model to see if the average number of hours per week (x) helps figure out y by using the least squares line. We test the null hypothesis that the slope (β1) is equal to 0 or less than 0. In other words‚ it means that average number of hours per week and work-life balance score do not have a linear relationship.
