... that the result is statistically significant at the 5% level. (c) Since the P-value is greater than 0.01, we say that the result is not statistically significant at the 1% level. (d) At the 5% level, we would reject H 0 and conclude that the random number generator does not produce numbers with an a ...

Estimating Geometric Means Using Data from a Complex Survey
... If you use SAS/STAT® 12.1 or later, you can estimate geometric means by specifying the ALLGEO statistic keyword in the PROC SURVEYMEANS statement. If you use a release prior to SAS/STAT12.1, none of the SAS/STAT survey procedures directly compute geometric means. However, with a little programming y ...

12.1 Inference for Linear Regression
... For their second-semester project, two AP Statistics students decided to investigate the effect of sugar on the life of cut flowers. They went to the local grocery store and randomly selected 12 carnations. All the carnations seemed equally healthy when they were selected. When the students got hom ...
