C. To test the null hypothesis that computer programmers' college major is not related to their programming capabilities, the work of 100 randomly chosen programmers was rated as either weak or strong. The following crosstabulation was obtained: Programming Capability Major Weak Strong Humanities: 1212 Science: 12 24 Business: 24 16 1. If the null hypothesis is correct, how many humanities majors with strong programming capability would we expect to find in our sample? That is, what is the expected frequency for that cell? 2. The computed value of x (chi-square) for this table is 5.45. Should the null hypothesis be rejected at the .05 level of significance? 3. Treating college major as the independent variable, calculate and interpret an appropriate measure of association 4. Using the appropriate percentages, show which major has the weakest programming capability.
