At birth according to the data the average neonate will be 28.8 inches. This is larger than the average

that is around 20 inches.

[email protected]

Using this data, at the of 27 an average human being would be ~96.79 inches or around 8 feet. This

could not possible be correct because humans peak their physical development during puberty.

US Carbon Dioxide Emissions

The X value represents the year and the Y value represents the annual carbon dioxide emission in

teragrams.

lm@"RSquared"D0.966382

In terms of RSquared the linear model is a pretty good fit to the data because it is close to 1. Visually

its an alright fit to the data.

The predicted estimated emissions according to the linear model do not accuratley display the actual

estimated carbon dioxide emission. The linear model may have broken down because of environmen-

tal laws that have been passed to reduce carbon dioxide emissions in the US.

Life Expectancy

The X value represents age and the Y value represents the life expectancy at the corresponding age.

lm@"RSquared"D0.984809

Visually and in terms of RSquared the linear model is a good fit. The Rsquared value is very close to 1

so it is a good fit.

[email protected]

At the age of 0, the life expectancy is 75.2. This suggests that the average human is expexted to live

75.2 years given a normal development. This doesn’t fit very well with the data because humans now a

days do live longer than 75 years seeing as the data has an expected life expectancy all the way up to

100 years old.

lm@"RSquared"D0.995437

Visually and in terms of RSquared the linear model fits very well with the data. The linear model sug-

gests that the estimated annual rate of increase of world population is 76,155,000.

Solve@lm@xD � 9 000 000 000, xD88x → 2038.39<<

The linear model suggest the world will reach 9 billion people sometime in the year of 2038. I don’t

think this is reasonable because as a planet today we can barely sustain our resources with our current

population. I believe that in the future we may experience population control like in China.

Solve@lm@xD � 0, xD88x → 1920.21<<

The linear model suggests that in 1920 the world population was 0. This is definitley not reasonable as

humans have been occupying this planet for about 200,000 years.

The linear fumction for TX’s data gives calculations that are slight off from the collected data. This also

happens with CA’s linear model and actual collected data.
