Answer 1

load("tempdata.RData")

range(tempdata$temp)

## [1] 61.6 74.0

max(tempdata$year)

## [1] 2015

max(tempdata$temp)

## [1] 74

min(tempdata$temp)

## [1] 61.6

plot(tempdata$year, tempdata$temp, xlab = "Recorded Years of October", ylab = "Recorded Average Temperatures in Fahrenheit", main = "Average Recorded Temperature of October in Los Angeles")

model3 <- lm(tempdata$temp ~ tempdata$year, data = tempdata)

abline(model3, col = "red", lw = 3)
