Question 68394:
Height(in):65,66,67,66,62,70,63,65,60,64,67,63,65,69,67,68,62,63,63,70,74,58,63,74
Shoe size:9.5,8.5,12,11,7,10,10,8,8,9,10.5,10,9.5,11,9,9.5,10,10,9,12.5,14,5,6.5,12
2)Identify the dependant and the independant variable.
4)How do u kno where the best fit line is?
6)Write an equation for ur line in point intercept form.
7)Rewrite the equation in standard form.
8)Estimate the shoe size for the following heights. Tell whether u would use linear or interpolation or linear extrapolation.height:66.5 - shoe size?
77 - shoe size?
80 - shoe size?
58 - shoe size?
10)Describe the pattern indicated in ur scatter plot. Do u think this pattern will continue for ever/ why or why not?
I need this information by tomarrow afternoon around about 5.00p.m Our teacher gave us a surprise project.

Height(in):65,66,67,66,62,70,63,65,60,64,67,63,65,69,67,68,62,63,63,70,74,58,63,74
Shoe size:9.5,8.5,12,11,7,10,10,8,8,9,10.5,10,9.5,11,9,9.5,10,10,9,12.5,14,5,6.5,12
2)Identify the dependant and the independant variable.
Dependent is shoe size; Independent is height.
--------------------
4)How do u kno where the best fit line is?
You could generate a scatter-plot to see the pattern.
----------------------
6)Write an equation for ur line in point intercept form.
Using the Linear Regression capability of a TI-83 calculator I get:
shoe size = 0.395(height)-16.242
--------------------------
7)Rewrite the equation in standard form.
395(height)-1000(shoe size)=16242
---------------------------
8)Estimate the shoe size for the following heights. Tell whether u would use linear or interpolation or linear extrapolation.
height:66.5 - shoe size=10.008
.........77 - shoe size=14.152
.........80 - shoe size=15.327
........ 58 - shoe size=6.6525
10)Describe the pattern indicated in ur scatter plot. Do u think this pattern will continue forever/ why or why not?
Forever: No
Why????? height is limited no matter what living creature you talk about
so shoe size will be limited also.
