The alternative hypothesis should state what the researcher is trying to prove or find evidence for. In this case, option A is the appropriate alternative hypothesis because it states that the population proportion is less than 0.65, which would be evidence against the null hypothesis that the population proportion is equal to or greater than 0.65. Option B does not work as the alternative hypothesis because it only refers to the sample proportion, not the population proportion. Option C is incorrect because it is not stating anything that can be tested or proven through the statistical analysis. Option D is similar to option B and does not refer to the population proportion.
