Using the image answer the following.Find the probability that a randomly selected hoysehold in North America uses greater than 161 gallons of water per day. Calculate the z-vaule with the formula and the probability with the z-table or calculator. **Section 2.** Suppose that you work for a government sector for water resources management. Your section is responsible for estimating the required amount of water for household use. Assume that the volume of daily water use per household in North America follows a normal distribution. The mean volume of daily water use is 138 gallons per household and the standard deviation is 46 gallons.

Mean()=138standard deviation()=46
