4.22 Thanksgiving spending, Part II: Exercise 4.14 provides a 95% confidence interval for the average spending by American adults during the six-day period after Thanksgiving 2009: ($80.31,$89.11).

A local news anchor claims that the average spending during this period in 2009 was $100. What do you think of her claim?

There is no problem with the news anchor's claim
Her claim is wrong since $100 is not contained in the confidence interval
Her claim is unsupported by the confidence interval since $100 is not contained in the confidence interval
