One-sample t-Interval for a mean Two-sample t-Interval for a mean One-sample z-Interval for a proportion Two-sample z-Interval for a proportion Matched pairs t-Test One-sample t-Test for a mean Two-sample t-Test for a mean One-sample z-Test for a proportion Two-sample z-Test for a proportion ANOVA Linear regression A study compared the toxicity on flies of four different types of selenium. The number of dead flies was counted and the selenium type (type 1, 2, 3, or 4) was recorded for each observation. The researchers want to know if the toxicities differ between selenium types You'd like to see if there is a difference in the mean incoming SAT score of incoming freshmen among all of the five colleges O A food distributor wants to know if new robots being used to fill the 8 oz. pasta packages in a pre-packaged food kit are overfilling the packages

Answer 1

DATE : _IL To study the sclationship between the no. of Japanese belt beetle grubs & % organic matter in the soil, we can fit a linear Regression to give the variation of no. of Japanese beetle grubs - depending Ton % Vorge ling on % organic matter To study is the difference between the toxicities of 4 selenium types is significant or not, we can use ANOVA to test the equivalence of mean toxicities of 4 types .. | Mean incoming SAT score of freshmen. among 5 different alleged can be tested by ANOVA To test is the mean weight of the packages is more than ook or not, we can use one sample t-test for a mean 4
