Question

A USA Today article about an experimental nasal spray vaccine for children stated, “In a trial involving 1602 children only 14 (1%) of the 1070 who received the vaccine developed the flu, compared with 95 (18%) of the 532 who got a placebo.” The accompanying TI-83/84 Plus calculator display results from a test of the claim that the vaccine had no effect. Identify the test statistic and P-value. What should you conclude about the claim?
