Do people who work for non-profit organizations differ from those who work at for-profit companies in terms of their job satisfaction? Seperate random samples were collected by a polling agency to investigate this difference. The following will wall you through some of the steps involved in testing the null hypothesis of "no difference."
a)Is a two-sided or a one-sided alternative hypothesis more appropriate here?
b) Find the p-value of the observed difference.
c) State a conclusion regarding rejection or non-rejection of the null hypothesis.
