A study conducted at Ateneo de Naga University revealed that students who attended class 95 to 100% of the time usually received an A in the class. Students who attended class 80 to 90% of the time usually received a C+ to B+ in the class. Students who attended class less than 80% of the time usually received a D or an F or eventually withdrew from the class. In this research in AdNU with 5000 students in which 100 students participated in the survey, what is the parameter of the study? a. 80% b. 80 - 90% c. 100 d. 95 - 100 % e. 5000
Elephants and hippos We removed humans from thescatterplot in Exercise 31 because our species was anoutlier in life expectancy. The resulting scatterplot showstwo points that now may be of concern. The point in theupper right corner of this scatterplot is for elephants, andthe other point at the far right is for hippos.a) By removing one of these points, we could makethe association appear to be stronger. Which point?Explain.b) Would the slope of the line increase or decrease?c) Should we just keep removing animals to increase thestrength of the model? Explain.d) If we remove elephants from the scatterplot, the slopeof the regression line becomes 11.6 days per year. Doyou think elephants were an influential point? Explain.

A gardener is interested in seeing if sunlight and fertilizer type interact so that the effect of fertilizer type depends on the amount of sunlight that plants receive. The gardener randomly assigns half of the plants to be in sunlight and half the plants to be in shade. The gardener also randomly assigns half of the plants to receive the new fertilizer and half to receive an old fertilizer. After a month, the gardener measures plant height. 1 What hypothesis test would be most appropriate for answering this research question and why? 2 What are the independent and dependent variables (if any)? 3 How many levels do the independent variable(s) have?
