If I studied the relationship between class size and student achievement, what kind of research design would I use?
A recent study randomly selected women from various countries around the world and collected information about diet and health. The women who at a Paleo diet had lower rates of Osteoporosis when compared to the other women in the study.
A. Which is the explanatory variable and why.
B. Which is the response variable and why.
C. Write a conclusion appropriate for this type of study that describes the relationship between the explanatory and response variables.
The National Highway Traffic Safety Administration requires each U.S. state to carry out an observational study to assess the level of seat belt use in the state. One report
summarized data from a study done in a certain state. Unfortunately, the "sex" variable provided very little information, and only indicated that it collected the values Female
and Male; it may be that this refers to the gender identity of the respondent. The proportions in the accompanying table are based on observations of over 25,000 drivers and
passengers.
Male
Female
Uses Seatbelt
0.422
0.452
Does Not Use Seat Belt
0.078
0.048
Assume that these proportions are representative of adults in this state and that an adult from this state is selected at random.
(a) What is the probability that the selected adult uses a seat belt?
(b) What is the probability that the selected adult uses a seat belt given that the individual selected is male?

The company is adding a special aeration treatment as a low-cost extra service option, which it hopes will help attract new customers. Management is planning to promote this new service in two media: radio and direct-mail advertising. A media budget of $4,000 is available for this promotional campaign. Based on past experience in promoting its other services, GreenLawns has obtained the following estimate of the relationship between sales and the amount spent on promotion in these two media: S = -2R2 − 12M2 − 9RM + 20R + 39M, Where S = total sales in thousands of dollars R = thousands of dollars spent on radio advertising M = thousands of dollars spent on direct-mail advertising GreenLawns would like to develop a promotional strategy that will lead to maximum sales subject to the restriction provided by the media budget.
