6.The proprietor of a greenhouse claims that its pots of lilies average 6.0 buds, with a standard deviation of 0.4 buds. If a random sample of 12 pots of lilies from a large number of pots of lilies has a mean of 5.8 buds, does this deny the proprietor's claim of the mean number of buds at the 0.05 level of significance?
