A blogger claims that U.S. adults drink an average of 40 ounces (that's five 8-ounce glasses) of water per day. Researchers wonder if this claim is true, so they ask a random sample of 24 U.S. adults about their daily water intake. A graph of the data shows a roughly symmetric shape with no outliers. What are the appropriate hypotheses for a significance test in this setting? Ho : µ = 40, H. : µ # 40 where u = the true mean daily water intake that a U.S. adult drinks per day. Ho : µ = 40, Ha :µ < 40 where µ = the true mean daily water intake that a U.S. adult drinks per day. Ho : µ 2 40, Ha :µ < 40 where µ = the true mean daily water intake that a U.S. adult drinks per day. Ho : µ < 40, H : µ > 40 where µ = the true mean daily water intake that a U.S. adult drinks per day.

Question
A blogger claims that U.S. adults drink an average of 40 ounces (that's five 8-ounce glasses) of water per day. Researchers
wonder if this claim is true, so they ask a random sample of 24 U.S. adults about their daily water intake. A graph of the data
shows a roughly symmetric shape with no outliers.
What are the appropriate hypotheses for a significance test in this setting?
Ho : µ = 40, Ha : u + 40 where u = the true mean daily water intake that a U.S. adult drinks per day.
Ho : µ = 40, Ha : µ < 40 where u = the true mean daily water intake that a U.S. adult drinks per day.
Ho : u 2 40, Ha : µ < 40 where u = the true mean daily water intake that a U.S. adult drinks per day.
O Ho : µ < 40, Ha : µ > 40 where u =
the true mean daily water intake that a U.S. adult drinks per day.
