In a study of Americans from a variety of professions were asked if they considered themselves left-handed, right-handed, or ambidextrous. The results are given below:
1. Test for an association between handedness and career for these five professions. What do you conclude at the 5% significance level? What do you conclude at the 1% confidence level? Make sure you show all the steps.
2. Can we conclude, at the 5% significance level, that left-handedness is equally distributed among the five professions? Make sure you show all the steps.
