For each of the following scenarios, would a one-way analysis of variance be the most appropriate statistical procedure(one-way ANOVA)? Explain why or why not.

A. The marketing team for a nation-wide travel agency wants to know if adults with high school, associates, bachelors, masters, and doctoral degrees differ in terms of the amount of money they spend on travel annually.

B. A bakery wants to know if men, women, and children differ in terms of whether or not they like red velvet cupcakes.

C. Medical researchers want to compare the effectiveness of a calcium supplement, a vitamin d supplement, a calcium + vitamin d supplement, and a placebo pill at preventing osteoporosis in women in their early 80s. They obtain a sample of 100 women who are 80 years old. The women are randomly assigned to receive one of the four treatments. After 5 years the researchers record the proportion of women in each treatment group who have been diagnosed with osteoporosis.

D. An educational researcher wants to compare the effectiveness of three different instructional methods. Students are randomly assigned to receive one of the three instructional methods. After four weeks of instruction their knowledge is measured using an exam worth up to 100 points.

E. A group of researchers have measured the wrist diameter, wrist flexibility, and body mass index of 50 adult males. They want to examine the relationships between the three variables.
