In Chapter 8 we used methods of estimating the value of a parameter.. In this chapter, we are drawing inferences about the parameter by making decisions concerning the value of the parameter. Two Hypothesis:. STAT 250. Dr. Kari Lock Morgan. SECTION 4.3. Significance level (4.3). Statistical conclusions (4.3). p-value and H. 0. If the p-value is small, then a statistic as extreme as that observed would be unlikely if the null hypothesis were true, providing significant evidence against H. How does a hypothesis begin?. What do you do with it?. How do you make one?. How does a hypothesis begin?. Scientists make lots of observations. This leads them to form scientific questions about what they have observed. Each scientist creates an explanation – or hypothesis – that he or she thinks will answer the question.. Hypothesis Testing. Test of hypothesis - Test whether a population parameter is less than, equal to, or greater than a specified value.. Remember an inference without a measure of reliability is little more than a guess.. 1. Contents:. Tests of significance for small samples. Student’s t- test. Properties of t-Distribution. The t- table. Application of the t-Distribution. To test the significance of . Mean of a random sample. Ho - this hypothesis holds that if the data deviate from the norm in any way, that deviation is due strictly to chance.. Alternative hypothesis. Ha - the data show something important.. Doing decision = accept/reject Ho (the decision centers around null hypothesis). The difference between a sample and a population. Null and research hypotheses. What is a good hypothesis. This week. 2. Hypothesis. An educated guess. Research questions .  hypothesis. A good hypothesis translates a problem or research question into a form that is more amendable to testing. Q. uestion.
