Question 7 of 9 < -/1 E Current Attempt in Progress The mean consumption of water per household in a city was 1231 cubic feet per month. Due to a water shortage because of a drought, the city council campaigned for water use conservation by households. A few months after the campaign was started, the mean consumption of water for a sample of 92 households was found to be 1151 cubic feet per month. The population standard deviation is given to be 248 cubic feet. a. Find the p-value for the hypothesis test that the mean consumption of water per household has decreased due to the campaign by the city council. Would you reject the null hypothesis at a = 0.05? Round your answer to four decimal places. p-value = We Ho- b. Make the test of part a using the critical-value approach and a = 0.05. Round your answer for z to two decimal places.
