Which statement most accurately explains inferential statistics?
Which is the most accurate definition of the term “population” as it is used in statistics?
To determine the ideal subsample size for an experiment, scientists need only consider the size of the entire population.
Suppose you have a corn harvest and the confidence interval of the sugar content is calculated to be 75 ± 4 mg/g. The range of values for the estimate is _________ mg/g.




What is statistical significance?
Which is the best way to select a subsample of corn ears from your cornfield in order to draw conclusions about your entire corn harvest for the season?
Random sampling is important for all of the following reasons EXCEPT
Assume you are comparing two harvests of corn, one where the mean sugar content is 75 ± 3 mg/g and the other with a mean sugar content of 80 ± 4 mg/g. How would you determine if difference in the sugar content of these two subsamples is statistically “significant”?
Assume you’ve tracked the mean sugar content of corn for the last 10 harvests and you’ve also tracked the mean average rainfall during the growing periods. The two sets of data, known as variables, appear correlated to each other. Can you also say there is also causation?
Two variables might show a correlation if they
