The following table shows the results from an investigation considering level of education and business success. Education level Graduate Undergrad Postgraduate Totals High School certificate degree No success Business Low success success Success High success Totals 35 30 41 25 131 29 56 28 41 26 124 35 52 150 24 41 156 225 38 133 63 171 72 182 636 At a 2.5% level with 9 degrees of freedom, the critical value is 19.023. Test at a 2.5% level whether there is a link between education level and business success. In your work include the expected frequency table
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.

### Education Level vs. Business Success
| Business Success | High School | Graduate Certificate | Undergrad Degree | Postgraduate | Totals |
|------------------|-------------|----------------------|------------------|--------------|--------|
| No Success | 35 | 30 | 41 | 25 | 131 |
| Low Success | 28 | 41 | 26 | 29 | 124 |
| Success | 35 | 24 | 41 | 56 | 156 |
| High Success | 52 | 38 | 63 | 72 | 225 |
| **Totals** | **150** | **133** | **171** | **182** | **636**|
### Statistical Analysis
- Testing at a 2.5% significance level with 9 degrees of freedom.
- The critical value to determine significance is 19.023.
- The task is to evaluate if a significant link exists between education level and business success. This involves calculating the expected frequency table and comparing it to the observed frequencies in the table above.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdff7b543-7c53-4567-b2e2-82ba64a4a215%2Fc285f0c6-b850-4724-b773-3e7bb275ef1b%2Ffjp1lq9_processed.jpeg&w=3840&q=75)
