An investigation carried out to study the toxic effects of mercury was described in the article "Comparative Responses of the Action of Different Mercury Compounds on Barley" (International Journal of Environmental Studies [1983]). Eight different concentrations of mercury were compared with respect to their effects on average dry weight (per 100 seven- day-old seedlings). The basic experiment was replicated 4 times for a total of 32 observations. The article reported an ANOVA F test statistic of 2.215. i. State the null hypothesis H, and alternative hypothesis Hq. ii. Determine the degree of freedoms between groups, df, and degree of freedoms within groups, df2.

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

Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

Addition
