... • Do the contents of bottles of catsup have a net weight below an advertised threshold of 16 ounces? • To test this 25 bottles of catsup were selected. They gave a net sample mean weight of X 15.9 . It is known that the standard deviation is .4 . We want to test this at significance levels 1% ...

... normally distributed with mean µ. A representative of a consumer advocate group wishes to see if there is any evidence that the mean net weight is less than advertised and so intends to test the hypotheses H0: µ = 14, Ha: µ < 14. To do this, he selects 16 bags of this brand at random and determines ...

... • Analysis of variance (ANOVA) is used as a test of means for two or more populations. The null hypothesis, typically, is that all means are equal. • Analysis of variance must have a dependent variable that is metric (measured using an interval or ratio scale). • There must also be one or more indep ...
