Solution:
Part A
The line of best fit for a five year children is given as
When children is 5 , years old, average that children will sleep each night
can be calculated by , putting, x=5 in above equation
Average sleep of 5 year old children , given by line of best fit= 13.5 hours
But it is given that, Average that a five year old children sleep= 10 hours
Difference between calculated and Actual = 13.5 - 10 = 3.5 hours, which is not so large,for a five year old children, but a large value, showing that it is not a reasonable estimate.
Part B
The line of best fit for a 20 year old is given as
When adult who is 20 , years old, average that adult will sleep each night
can be calculated by , putting, x=20 in above equation
Average sleep of 20 year old adult , given by line of best fit= 11.625 hours
But it is given that, Average that a 20 year old adult sleeps= 7 hours
Difference between calculated and Actual = 11.625 - 7 = 4.625 hours, which is quite large, for an adult, showing that it is not a reasonable estimate.
