Stick with the phrase "95% confident" and avoid using the word "probability" and chances are that no one (not even expert statisticians) will be too offended. 6, which describes another way to make statistical inferences about population means—hypothesis testing—let us consider whether we can now forget the normal distribution. The calculations in this section are based on the central limit theorem, which does not require the population to be normal. We have also seen that t-distributions are more useful than normal distributions for calculating confidence intervals.
Deviation 21,728 Write down the null and alternative hypotheses for this problem. Then specify the rejection region for conducting a two-tail test at significance level 5%. Based on the computer output, would you reject or fail to reject the null hypothesis for this test? ) (g) In a hypothesis test, is it true that the smaller the p-value, the less likely you are to reject the null hypothesis? Explain. CHAPTER 2 SIMPLE LINEAR REGRESSION In the preceding chapter, we considered univariate data, that is, datasets consisting of measurements of just a single variable on a sample of observations.
Look up t-table: m ~E ^ sy/s/n = 2 Z , 8 S . 40. 045 (from Table B. 8 Relationships between critical values, significance levels, test statistics, and p-values for two-tail hypothesis tests. 5th percentile in this case because this is a two-tail test, so we need half the significance level in each tail). 05. 40 falls in the rejection region, we reject the null hypothesis in favor of the alternative. 05), so we reject the null hypothesis in favor of the alternative. • Interpret in the context of the situation: The 30 sample sale prices suggest that a population mean of $255,000 seems implausible—the sample data favor a value different from this (at a significance level of 5%).
