Null hypothesis (Ho): Population parameter EQUALS to a hypothesized value.

Only symbols of equivalence such as =, ≥ and ≤ might be used in the null hypothesis. The alternative hypothesis contains symbols that are contradictory to the null hypothesis such as ≠, < and >.

The table below simplifies the process of setting up the null and alternative hypothesis for one population mean and proportion:

  1. For rational functions such as f(x) = 1/x, f(x) is undefined when x=0.
  2. For logarithms such as f(x) = ln x, f(x) is undefined when x≤0.
  3. For square root function such as f(x) = square root (x), f(x) is undefined when x<0.
