The null hypothesis should state that there is no significant difference between the current satisfaction rate and the previous satisfaction rate. Therefore, the null hypothesis should be H0: p = 0.857. The alternative hypothesis should state that there is a significant difference between the current and previous satisfaction rates. As we are concerned that the satisfaction rate may have decreased, the alternative hypothesis should be HA: p < 0.857. Therefore, the best choice is C.
