A new medication is being developed to treat severe morning sickness in pregnant women. The information below was generated from a small sample size (n= 6) and shows the number of times a woman with morning sickness vomited both before and after treatment. Set up and interpret the results of a sign test at the alpha equals 0.05 level to determine if there is a difference in symptoms before and after treatment. Preg women before tx after tx difference sign 1 8 3 2 10 7 3 6 5 4 8 10 5 11 10 6 8 2 A) We fail to reject H0, which states the median difference in the # of vomiting episodes in a day before and after treatment are equal because 1 is greater than the critcal value 0 for a sign test with a population of only 6 individuals. B) We fail to reject H0, which states the median difference in the number of vomiting episodes in a day before and after tratment are equal because 5 is greater than the critical value 0 for a sign test with a population of only 6 individuals. C) We reject H0 in favor of H1, which states the median difference in the number of vomiting episodes in a day before and after tx are not equal because 1 is greater than the critical value 0 for a sign test with a population of only 6 individuals. D) We reject H0 in favor of H1, which states the median difference in the # of vomiting episodes in a day before and after tx are not equal because 5 is greater than the critical value 0 for a sugn test with a population of only 6 individuals.
