The null hypothesis is that the proportion is 28%, and the alternative hypothesis is that it is more than 28%. Using a one-sample z-test for proportions, the test statistic is calculated, and the P-value is found to be 0.0026, which corresponds to the probability of observing a sample proportion of 39% or more if the true proportion is 28%.
