In general, Latinos and Caucasians use social media networks equally, but there are some differences in their preferences for specific social media sites (www.pewresearch.org, February 5, 2015). In particular, Instagram is more popular among Latinos while Pinterest is more popular among Caucasians. Kate Dawson, a junior in college, decides to test if similar differences exist among students on her campus. She collects data on 400 students cross-classified by Race (Latinos versus Caucasians) and Social Media Preference (Instagram versus Pinterest). The results are shown in Table 11.9. At the 10% significance level, determine whether the sample data support racial differences in social media preferences.
