Question

A study was done on children, aged 6 months to 18 years, who had nonlethal scorpion stings. Each child was randomly assigned to receive an experimental antivenom or a placebo. "Good" results were no symptoms after four hours and no detectable plasma venom. The alternative hypothesis is that the antivenom leads to improvement. The p-value for a one-tailed Fisher's Exact Test with the accompanying data (first table) is 0.008. Complete parts a through c below Click the icon to view the regular and altered antivenom data. O B. O C. The p-value would be larger, because the results are less extreme in the direction of the antivenom working The p-value would be smaller, because the results are less extreme in the direction of the antivenom working D. The p-value would be smaller, because the results are more extreme in the direction of the antivenom working b. Suppose the study had turned out differently, as in the third table. Would Fisher's Exact Test have led to a p-value larger or smaller than 0.008? Explain. Choose the correct answer below. 0 A. The p-value would be smaller, because the results are more extreme in the direction ofthe antivenom working O B. The p-value would be smaller, because the results are less extreme in the direction of the antivenom working C. The p-value would be larger, because the results are less extreme in the direction of the antivenom working 0 D. The p-value would be larger, because the results are more extreme in the direction of the antivenom working c. Try the two tests, and report the p-values. Search for a Fishers Exact Test calculator on the Internet, and use it. Were the predictions right? The one-tailed p-value for the test in part a is and the two-tailed p-value for the test in part a isRound to three decimal places as needed.)

Explanation / Answer

one tail p value=0.468

Result not significant if p<0.05

For second tail p value=0.936

Result not significant if p<0.05
