A psychologist believes that the frequency that a person engages in sexual activity without a partner depends upon what type of relationship that person may be in.  She sampled 5455 randomly selected adults and asked them what type of relationship they were in and how often per week they engaged in sexual activity without a partner (i.e., alone).  Do the data support her hypothesis?  Use the SPSS output below to perform the appropriate six-step test at the 5% significance level using the P-value approach, and also be sure to explain your answer to the question "Do the data support her hypothesis?".
