Suppose that major new legislation was recently passed by the government. Fourteen economists were sampled and asked to predict if the national economy would improve during the next 12 months compared to its present state as a result of this legislation. Eight of the economists predicted an improvement, two economists predicted no change, and four economists predicted a decline in the economy. Conduct a hypothesis test at the 0.10o significance level to determine if the majority of economists predict an improvement in the economy. The correct analysis would be a Multiple Choice chi-square test Wilcoxon signed-rank test Kruskal-Wallis test sign test based on the binomial distribution

Percentage

A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.

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

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