ANOVA Test 15. A researcher believes that students do better on a reading test when hearing a constant background sound. She divides a group of students into three random groups, has them read a passage (with different background sounds), and then gives them a test. The following are her results: Constant Sound 7 10 9. 4 Random Sound 3 8 7 4 1 No Sound 5 2 4 3 4 2 6 Can she say that there is a significant difference between any of the types of sounds? 16. A botanist wants to see if a new plant grows better in different types of sunlight. He counts the number of new leaves on the plant in one month, and gets the following results: Full Sun 14 23 11 14 17 21 20 31 Partial Sun 13 18 29 14 30 21 28 11 17 19 31 Shade 32 23 18 17 29 31 33 15 16 18 Can the botanist claim that the amount of light has an effect on how the plants grow?

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction
