An April 2004 article on HearTheIssues.com stated that Americans watch an average of 4.5 hours of television per person per day. If the standard deviation for the number of hours of television watched per day is 3.3 and a random sample of 235 Americans is selected, the mean of this sample belongs to a sampling distribution.

(c) What is the standard deviation of this sampling distribution? (Give your answer correct to two decimal places.)
