Question

In recent years there has been considerable discussion about the appropriateness of the body shapes and proportions of the Ken and Barbie dolls. These dolls are very popular, and there is some concern that the dolls may be viewed as having the "ideal body shape," potentially leading young children to risk anorexia in pursuit of that ideal. Researchers investigating the dolls' body shapes scaled Ken and Barbie up to a common height of 170.18 cm (5' 7") and compared them to body measurements of active adults. Common measures of body shape are the chest (bust), waist, and hip circumferences

Answer 1

These measurements for Ken and Barbie and their reference groups are presented in the table ATTACHED

Suppose that the researchers' scaled up dolls suddenly found themselves in the human world of actual men and women.

Convert Barbie’s chest, waist, and hips measurements to z-scores. Do these z-scores provide evidence to justify the claim that the Barbie doll is too thin of a representation of adult women? Justify your response with an appropriate statistical argument.

Answer 2

Unsure how to approach. Appreciate any advice!

Answer 3

basically you see how many z scores away the barbies measurements are from humans

Answer 4

you can find out what probability of the women and men have sizes close to the barbies in each areas of measurement

Answer 5

I will do a sample calculation for you

Answer 7

you can find the exact probabilities for the z scores you calculate from the z table, you should carry on and find the zscores for all the different areas they are measuring

Answer 8

Okay, think I got it. Thanks dan!

Answer 9

I wonder how that data accounted for obesity :/
