The CEO of a battery manufacturing company claimed thattheir batteries would last an average of 280 hours under normal use. Arsearcher randomly selected 20 batteries from the production line andtested them. The tested batteries had a mean life span of 250 hours with astandard deviation of 40 hours. Do we have enough evidence to suggest thatthe claim of an average of 280 hours is false?5. It was known that the number of tickets purchased bystudents at the ticket window for the volleyball match of two popularuziversities followed a distribution that has mean of 500 and standarddeviation of 8.9. Suppose that a few hours before the start of one of thesematches, there are 100 eager students standing in line to purchase tickets.If there are 250 tickets remaining, what is the probability that all 100sudents will be able to purchase the tickets they want?

Use z scores to compare the given values. The tallest living man at one time had a height of 225 cm. The shortest living man at that time had a height of 104.3 cm. Heights of men at that time had a mean of 173.55 cm and a standard deviation of 5.15 cm. Which of these two men had the height that was more extreme? Since the z score for the tallest man is z= and the z score for the shortest man is z= the V man had the height that was more extreme. (Round to two decimal places.)
