Question

Thanks for your help

Anthropologists use a linear model that relates femur length (em) to height (cm). The odetl allows an anthropologht to determine the height of an The samples uned to create the model ranged from a femar leneth of 38cm to a femar length of 51 cm. The data yielded the followi S individual whem only a partial sheleton (inckhadting the femar) is found Reighi-80.681 1923mu length) Part 1: (4 pts) Give the slope (2 pts) and interpret what it means in the context of the question 2 pts) Part 2: (4 pts) Give the y-intercept (2 pts) and interpret what it means in the context of the question (2 pts) Part 3: (6 pts) Uhe the model to predict the height of a man with a femr length of 54 cm (4 pts), then comment on the unelud of your solutien (2 s

Answer 1

a)
slope = 1.923
on average, when femur length increase by 1 unit ,
height increase by 1.923 unit

b)
intercept = 80.681
in means if femur length is 0 , on average height is 80.681

c)
y^ = 80.681 + 1.923* x
= 80.681 + 1.923 *54
= 184.523
