According to a 2008 survey by the Royal Society

According to a 2008 survey by the Royal Society of Chemistry, 30% of adults in Great Britain stated that they typically run the water for a period of 6 to 10 minutes while taking the shower http://www.rsc.org/ AboutUs/News/PressReleases/2008/EuropeanShowerHabits.asp

 

Suppose that in a recent survey of 400 adults in Great Britain, 104 stated that they typically run the water for a period of 6 to 10 minutes when they take a shower. At the 5% significance level, can you conclude that the proportion of all adults in Great Britain who typically run the water for a period of 6 to 10 minutes when they take a shower is less than .30?

 

 Use both the p-value and the critical value approaches.
