Questions 23 - 27 concern the following idea: A tea merchant claims that the packages they sell contain 500g of loose tea leaves. A consumer advocate doubts this claim, buys 100 randomly selected packages and weighs all of them. Based on the selected sample the consumer advocate obtains a sample mean of x=497, and a sample standard deviation of s = 8.2g.
