g Blue Ribbon taxis offers shuttle service to the nearest airport. You look up the online reviews for Blue Ribbon taxis and find that there are 17 reviews, six of which report that the taxi never showed up. Is this a biased sampling method for obtaining customer opinion on the taxi service? a)This is a biased sampling method for obtaining customer opinions because those who take the time to write an online review are likely to do so because they are upset with the service they received. b) There is not enough information to tell if this is a biased sampling method. c) This is a biased sampling method for obtaining customer opinions because those who take the time to write an online review are likely to do so because they are satisfied with the service they received. d) This is not a biased sampling method for obtaining customer opinions because those who take the time to write an online review are choosing to write the review without any incentive. If this is a biased sampling method, what is the likely direction of the bias? a) The direction of the bias is likely to underestimate the proportion of customers who have a negative opinion on the service. b) This is not a biased sampling method. c) The direction of the bias is likely to overestimate the proportion of customers who have a negative opinion on the service. d) The direction of the bias is likely to overestimate the proportion of customers who have a positive opinion on the service.

The competitive advantage of small American factories such as Tolerance Contract Manufacturing lies in their ability to produce parts with highly narrow requirements, or tolerances, that are typical in the aerospace industry. Consider a product with specifications that call for a maximum variance in the lengths of the parts of 0.0004. Suppose the sample variance for 30 parts turns out to be s2 = 0.0005. Use α = 0.05 to test whether the population variance specification is being violated.
