The null hypothesis is p = 0.68 while the alternative hypothesis will be that it's below that is p < 0.68.
First, let us understand the Null and Alternative hypotheses:
The null hypothesis is simply to predict that there is no effect of the relationship between the variables.
The alternative hypothesis is to state the research prediction of a relationship or effect. In this case, the newsletter publisher believes that below 68% of their readers own a Rolls Royce.
The null hypothesis is that the proportion of readers who own a Rolls Royce is equal to 0.68.
Null hypotheses = H₀: p = 0.68
The alternate hypothesis is that the proportion of readers who own a Rolls Royce is below 0.68.
Alternate hypotheses = H₁: p < 0.68.
Thus, the null hypothesis is p = 0.68 while the alternative hypothesis will be that it's below that is p < 0.68.
