Megan Cross and Tevy Nuon



Regression Project


A1.) Facebook World Domination



Table of months and facebook user acounts

x=months y=# of users

Exponential Regression




Equation: y=(428856.19193214)(1.1006779090265)^x



x=months y=# of users
a= 428856.1919 the average number of facebook users

b=a positive growth factor, the time for the # of people to increase

r=correlation between variable of a and b

r^2=means that the # of facebook users increases by that percent (99 %)




a) Now: y=(428856.19193214)(1.1006779090265)^74

y=519003389.9

about 51,900,390 people



b) In six months from now: y=(428856.19193214)(1.1006779090265)^80

y=922851229.4

about 922,851,229 people
