w <- 10.2
x <- 1.3
y <- 2.8
z <- 17.5
colors <- c("red", "blue", "green")
masses <- c(45.2, 36.1, 27.8, 81.6, 42.4)
dna1 <- "attattaggaccaca"
dna2 <- "attattaggaacaca"

Use them to print whether or not the following statements are TRUE or FALSE.

  1. w is greater than 10
  2. "green" is in colors
  3. x is greater than y
  4. Each value in masses is greater than 40.
  5. 2 * x + 0.2 is equal to y
  6. dna1 is the same as dna2
  7. dna1 is not the same as dna2
  8. w is greater than x, or y is greater than z
  9. x times w is between 13.2 and 13.5
  10. Each mass in masses is between 30 and 50.
