Note: For the questions below (Questions 14-15): For the hypothesis tests, specify (i) Null and alternative hypotheses, (ii) Form of the test statistic, (iii) Make the decision about rejecting or not rejecting Ho. For the CIs, provide a lower and upper bound 14. (24 points) In a recent medical journal, a medical researcher reported data on eight cases of umbilical cord prolapse. Umbilical cord prolapse is a life threatening condition that happens when the umbilical cord precedes the fetus' exit from the uterus during delivery. Oxygen and blood supply to the fetus can be diminished or cut-off and the baby must be delivered quickly. Ages of the eight mothers who experienced umbilical cord prolapse were 25, 28, 17, 26, 27, 22, 25, 30. The researcher believed that the mean age of women who experience umbilical cord prolapse is greater than 20. Assume that age of women at time of umbilical cord prolapse is normally distributed. (a) Using a Type I error rate of a=0.05, conduct an appropriate hypothesis test to determine if umbilical cord prolapse typically occurs when the birthing mother is over 20 years of age. (b) Construct a 95% C.I. for u (mean age of mother at time of umbilical cord prolapse)
