 Identify the appropriate hypothesis test for each of the following research situations labeled (a) - (d).  Make sure to label your responses clearly!

 

  1. A researcher conducts a study to determine whether there is a significant difference in life satisfaction between bisexual men and gay men.
  2. A researcher records the weekly alcohol consumption and the number of violent crimes committed by incarcerated adolescents. The researcher would like to determine whether there is a significant relationship between their teen’s alcohol
  3. A researcher would like to determine the effectiveness of her newly designed mnemonic training, a technique that is expected to improve memory. She selects a sample of n=30 participants, tests their memory skills then has them undergo the training for 4 hours. At the end of the training, participants’ memory skills are tested a second time.
  4. A researcher would like to determine whether gender (Male, Female) and sexual orientation (Gay, Bisexual, Heterosexual) affect frequency of orgasm.  It is suspected that men in general report more orgasms than women, and that LGB people overall report more orgasms than any other group. Nonetheless, the researcher believes that if both gender and sexual orientation are examined, participants that are female and heterosexual will have the lowest frequency of orgasms and participants that are male, and heterosexual will have the highest frequency of orgasms.
