Please only post your questions once. Repeating posts will not get a quicker response. In addition, it wastes our time looking over reposts that have already been answered in another post. I would also help to just use one name on your posts. Thank you.
See your later post.
An April 15, 2002 report in Time Magazine stated that the average age for women to marry in the United States is now 24.9 years of age. If the standard deviation is assumed to be 4.9 years, find the probability that a random sample of 33 U.S. women would show a mean age at marriage of less than or equal to 23.2 years. (Give your answer correct to four decimal places.)
