The null hypothesis should have a statement of equality. Another way of thinking of it is that the null hypothesis is a statement of "no difference."



In this context, Leo's null hypothesis should be that the employees at his company have tea preferences that are no different than the reported value. In other words, he should assume that the proportion of them that prefer green tea to black tea is equal to 30%


H_{0}: The proportion of all tea-drinkers at the company that prefer green tea to black tea is equal to 30%
