  1. Most statistical tools use a .05 significance level. Explain what that means.

  1. Men versus women were compared for their level of willingness to disclose their sexual history to a dating partner when the relationship begins to get serious. Their scores are shown below. Using a t-test as the statistical tool, write a null hypothesis and an alternative hypothesis for this example. From the data below, fill out the chart and follow the 11 steps on page 342 to compute the t-test, compare it with t critical, answer the hypothesis, and interpret your findings.
