Students in a statistics class were asked to count the number of scars they had on their dominant hand and on their non-dominant hand. Below is a table to summarize the data that was collected.
| Non-Dominant | Dominant | Difference (non-dom - dom) | |
| n | 30 | 30 | 30 |
| x | 2.72 | 1.92 | 0.8 |
| s | 3.007 | 2.326 | 2.363 |
Do we have statistically significant evidence that, on average, people have more scars on their nondominant hand?

In one statistics class, students were given one homework assignment. The professor asked students to find an example of a multinomial population and then to develop a hypothesis test. One student found an example – He selected four classes in fall 2010: Management, Accounting, Finance, and Economics. He computed the proportion of students who received an A grade for each class in fall 2010. The proportion of students who received an A grade in Management (M), Accounting (A), Finance (F),...

when looking for a romantic partner. Two samples were collected: 30 adolescent males (age 13-15) and 30 male college students (age 19-32). Each subject was asked to identify the single most important factor determining whether he is likely to pursue a romantic relationship with a new female acquaintance. The number of men who chose each category are shown below. The 60 cases have been entered into a SPSS file called Ch17n21.sav. Run a Chi-square test for Independence using Analyze, Descriptive...
