3. In a California study, Dean Lester Breslow and Dr. James Enstrom of the University of California at Los Angeles' School of Public Health concluded that the following 7 simple health rules a man's life can be extended by eleven years on the average and a woman's life by seven. These 7 rules are: no smoking, regular exercise, use alcohol moderately, get seven to eight hours of sleep, maintain proper weight, eat breakfast, and do not eat between meals. In how many ways can a person adopt 5 of these rules to follow a) if the person presently violates all 7 rules b) if the person never drinks and always eats breakfast?

1. In a psychological study of distance perception, introductory psychology class volunteers were given either 5 or 10 extra credit points depending on their level of participation in the experiment. They walked along paths laid out along hallways in the psychology building, and were asked to judge the distance they had walked. Each path distance was between 100 and 200 feet in length, and contained from two to seven 90 degree turns. The investigators also kept track of class standing (freshman, sophomore, junior, or senior) of each participant. For each of the variables in the study, determine whether it is qualitative or quantitative. For each quantitative variable, determine whether it is discrete or continuous. For each qualitative variable, determine whether it is nominal or ordinal. [4 pts.] a. The true length of the path b. The amount of credit given to volunteers c. Class standing d.

A local health department believes that a store is merchandising its cereal aisle in a way that puts sugary cereal brands at eye level for children. The store claims that it is not considering sugar content and is stocking the shelves based on other factors. An inspector visited the store and recorded the sugar content per serving listed on the boxes (sugar content for each box is listed under the shelf where that box of cereal is located).

How many experimental units were there be if there were 10 boxes per brand on the shelf? Explain your answer. [hint: all the boxes for each brand will be in one place] c) State the null hypothesis and create an ANOVA table based on sugar…
