Describe a hypothesis test study that would help your work or conclusions in some way. Describe what variable would be tested and what would be your guess of the value of that variable. Then include how the result, if the null were rejected or not, might change your conclusions or actions in some way.

In everyday terms, a confidence interval is the range of values around a sample statistic (such as mean or proportion) within which clinicians can expect to get the same results if they repeat the study protocol or intervention, including measuring the same outcomes the same ways. As you ask yourself, “Will I get the same […]

  1)  Test whether there is an association between a person’s gender and the prestige of their occupation.  Use the GSS2008 data set to perform an independent samples t-test on SEX and PRESTG80 (or PRESTG10 depending on the data set).
