Researchers recruited a sample of 40 female and 40 male heterosexual Caucasian undergraduate students from British universities for a study of the attractiveness of body types. Among adults, a body mass index (BMI, in kg/mz) value between 18.5 and 24.9 is considered healthy, but attractiveness may not be entirely about health. Using a 3D computer avatar, participants built what they considered the ideal body of an adult of their own gender. Consider the Minitab output for the mean ideal BMI of the women and then of the men. OneSample T N Mean StDev SE Mean 95% CI 40 18.850 1.?50 0.21? {18.290, 19.410) OneSample T N Mean SLDev SE Mean 95% C; 40 25.860 3.950 0.625 {24.597. 2?.123) From Barbie dolls to runway models, women in Western countries are exposed to unrealistically thin and arguably unhealthy body standards for their gender. Does the study provide evidence that young Caucasian women in British universities, on average, aim for an unhealthy ideal body type (corresponding to a BMI less than 18.5)? Obtain the P-value. Give your answer to four decimal places. P-value
