An important part of inferential statistics is hypothesis testing. As with learning anything related to mathematics, it is helpful to work through several examples. The following examines an example of a hypothesis test, and calculates the probability oftype I and type II errors. We will assume t...
3. Give an example of a hypothesis and a theory. The Scientific Method: Hypothesis and theory are both part of the scientific method. The scientific method is a way of thinking and approaching a problem; this problem could be a small one like "why is my car ...
Give an example of a null hypothesis. What would constitute a type I error for this hypothesis?Type I vs. Type II Errors:A type I error, also known as a false positive, is when a true null hypothesis is rejected. A type II error, known as a false neg...
TeachingHypothesis testingPowerSummary This article describes an example which is useful when teaching hypothesis testing in order to highlight the interrelationships that exist among the level of significance, the sample size and the statistical power of a test. The example also allows students to ...

Earlier research for the two methods indicates that o1 = 14 points and o2 = 15 points.Let μ1 and μ2 be the mean scores of the distribution of all scores using method 1 and method 2,respectively.To examine the validity of the teacher's claim,what should the alternate hypothesis be?
We need to determine a sample size N so that we can distinguish between a mean of 100 and a mean of 110. We know the standard deviation is 20. When we carry out a statistical test, we generally test a null hypothesis against an alternative hypothesis. We find a test statistic T, and...
Creating a null hypothesis and an alternative hypothesis, then performing a statistical test of significance are required.A hypothesis test can have left-, right-, or two-tailed distributions. The test statistic’s value, the critical value, and the confidence intervals are used to conclude. ...
