Do you drink the recommended amount of water each day? Most Americans don't! On average, Americans drink 5.4 eight-oz servings of water a day. A sample of 36 education professionals was randomly selected and their water consumption for a 24-hour period was monitored; the mean amount consumed was 46.8 oz. Assuming the amount of water consumed daily by adults is normally distributed and the standard deviation is 10.9 oz, is there sufficient evidence to show that education professionals consume, on average, more water daily than the national average? Use α = .05.

Multiply 5.4 by 8 to get in the same units.

Z = (score-mean)/SEm

SEm = SD/√n


Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability for your Z score.
