Recent studies have indicated that the typical New York City teenager spends $500 per year on attending movies. The distribution of amounts spent is normal, with a population standard deviation of $100. We select a random sample of 25 teenagers, and find that the mean amount they spent in the last year was $535. What is the likelihood of a finding a mean for a sample of 25 that is $535 or larger from the specified population?© BrainMass Inc. brainmass.com June 4, 2020, 1:48 am ad1c9bdddf
