Chapter9a--Hypothesis testing
... Hypothesis testing can be used to determine whether a statement about the value of a population parameter should or should not be rejected. The null hypothesis, denoted by H0 , is a tentative assumption about a population parameter. The alternative hypothesis, denoted by Ha, is the opposite of ...

From the same survey date one may calculate a smaller 90% confidence level for the proportion in the whole population of for instance in confidence interval 38% to 42%. All other things being equal, a surv ...

... The F statistic compares the variability of the sample means with the variability of individual scores within the samples. Because it is a comparison of variability, it’s called the Analysis Of Variance, or ANOVA. ANOVA was first used by Ronald Fisher, a British Mathematician, in the 1930s. The theo ...

Statistical Hypotheses
... Note: Since s and n are known from the sample data, so we have a good estimate of x , but we do not know since this is the parameter we are testing a claim about. In order to have a value for , we will always assume that the null hypothesis is true in any hypothesis test. Since the null hypoth ...
