I need 17.10 please

 

Exampme: 17.6

An attractive body.  The researchers recruited a sample of 40 female and 40 male heterosexual Caucasian college students from British universities for a study on the attractiveness of body types.  Among adults, a body mass index (BMI, in kg/m²) value between 18.5 and 24.9 is considered healthy, but attractiveness may not be solely due to health.  Using a 3D computer avatar, the participants constructed what they considered to be the ideal body of an adult of their own gender.  Here is the Minitab result for the mean ideal BMI for women (top) and men (bottom):5 One-sample T

N=40

Mean=18.850

Stdev= 1.750

SE mean= 0.277

95% CI

(18.290, 19.410)

 

One-sample t

N=40

Mean= 25.860

Stdev= 3.950

SE mean= 0.625

95% CI

(24.597, 27.123)

 

A) Interpret the confidence interval for women in context.  How does it relate to the definition of a healthy BMI?  (b) Interpret the confidence interval for men in context.  How does it relate to the definition of a healthy BMI?  (c) The researchers aim to answer the question of what constitutes an ideal body size.  Why might the study findings not be representative of all adults in general?  Logical attributes of the monarch

7.10
tiveness of body types. From Barbie dolls to runway models, women in Western
countries are exposed to unrealistically thin and arguably unhealthy body stan-
dards 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)?
(a) State the corresponding null and alternative hypotheses.
(b) Obtain the test statistic and P-value then conclude in context.
