An advertising firm wanting to target people with strong desires for success conducted a study to see if such people differed in the types of television shows they watched. Randomly selected participants recorded the shows they watched for a week, then their desire for success was assessed, and finally they were divided into two groups. Low Success seekers watched 8 comedies, 15 romances, 6 documentaries, 13 dramas, and 3 news shows. High Success seekers watched 3 comedies, 3 romances, 9 documentaries, 7 dramas, and 8 news shows. Using this data answer the following:

  • State the populations and hypotheses
  • Create a table for the data
  • Conduct a Chi-Squared for independence test using the SPSS program and post output file.
  • State the results using the proper APA format.
  • Is the distribution of type of shows watched different for participants having high and low desires for success?
