14. (6) A test was performed to determine if the proportion of public water sources that are safe for consumption differs from 0.80. That is, we tested Ho: p = 0.80 vs Ha: p # 0.80. In 64 out of 70 sampled sites, the public water sources were safe for consumption, and the test yielded a p-value of 0.02. What conclusion can we draw regarding the proportion of public water sources that are safe for consumption at the a = 0.01 level of significance? a. Because the p-value o, we conclude that the proportion of public water sources that are safe for con- sumption does not significantly differ than 0.80. c. Because the p-value o, we conclude that the proportion of public water sources that are safe for con- sumption is significantly different 0.80. e. Because the p-value
