Current Attempt in Progress College Students and Paying Jobs Exercise 2.16 introduces data from a survey that included 5204 fırst-year, full-time college students. Their responses to a question about whether they worked at a paying job while attending college are given in the table below. Assumed Paying job? Frequency Proportion Works on campus Works off campus 1436 0.25 1119 0.25 Does not work 2649 0.50 Total 5204 It is assumed that 50% will not work at a paying job, while 25% will work on campus and the other 25% will work off campus. (a) Test whether the data contradict the assumed proportions. Paying job? Expected Contribution Works on campus i i Works off campus i i Does not work i i Chi-square statistic = i (round to three decimal places) p-value = i (round to three decimal places) Choose conclusion from the following list: A. Reject Ho. Assumed proportions are accurate. B. Reject Ho. Assumed proportions are not accurate. C. Do not reject Ho. Assumed proportions are accurate. D. Do not reject Ho. Assumed proportions are not accurate. Conclusion (b) Which category contributes the most to the O statistic? For this category, is the observed value greater than or less than what is expected?

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.
