The null value is the value we would expect for the parameter if the null hypothesis was true. For a single proportion, the null value will be between 0 and 1. For difference of proportions, the null value will be 0. (Later, we will also include means and difference of means.) For each example below, determine if the parameter is a single proportion or a difference of proportions and state the null value. a) You want to know if 40% of the people will vote the upcoming election. The parameter is a proportion The null value = 0.4 b) You want to know if women are more likely to eat breakfast than men. The parameter is a difference of proportions v The null value =0 c) You want to know if divorce rates are higher in urban areas than in rural areas. The parameter is a difference of proportions The null value =0 d) You want to know if a majority of congressmen support an upcoming bill. The parameter is a proportion The null value - 0.
