Many alpine ski centers base their projections of revenues and profits on the assumption that the average alpine skier skis four times per year. to investigate the validity of this assumption, a random sample of 63 skiers is drawn and each is asked to report the number of times he or she skied the previous year. if we assume that the standard deviation is 2, can we infer at the 10% significance level that the assumption is wrong?
