Asked by Shayna
Use the 5-step hypothesis testing framework to answer the following 2 questions:
Step One: Stating the hypothesis
Step Two: Choosing the appropriate test statistic
Step Three: Developing a decision rule
Step Four: Calculating the value of the test statistic
Step Five: Stating the conclusion
Q1: A friend says at most only 50% of all people he has talked to have ever “unfriended” someone on Facebook (sample size 200). Your research finds 90% of Marketing Majors have (sample size 111). Are Marketing Majors more likely to be “unfriendly” than the average person?
Q2: On Facebook 3.8% of Male Marketing Majors have never unfriended someone while 15% of Female Marketing Majors have never unfriended someone. Does this mean Females are more friendly? (check SPSS datafile on blackboard for sample sizes)
