- Q4; Some of the results of a trial, carried out by the Department of Pharmacology/ Thi-Qar College of Medicine in 2010, of a new antihypertensive drug and methyldopa are shown below. Each patient received each treatment for a period of 8 weeks separated by a period of wash out on placebo. Change in systolic blood pressure Methyldopa + 10 + 08 - 33 + 19 + 31 Patient New drug - 10 - 09 + 04 + 04 + 04 1. 2. 3. 4. 5. 6. -30 12 7. 00 28 - 02 + 03 - 28 - 21 8. %3D 9. 10. 14 06 De these date show that any of these two drugs have a greater effect than the other?How is the hatching of water python eggs influenced by the temperature of the snake's nest? Researchers randomly assigned newly laid eggs to one of three water temperatures: hot, neutral, or cold. Hot duplicates the extra warmth provided by the mother python, and cold duplicates the absence of the mother. The table shows the result of the experiment. The researchers will use a chi-square test for homogeneity to analyze the findings. Hatching status Yes No Total Cold 16 11 27 Water Temperature Neutral Hot 38 75 18 56 104 Total 129 58 187 Which of the following is false? All of the conditions are met for conducting a chi- square test for homogeneity. The data came from 3 groups in a randomized experiment. All expected counts are at least 5. The 10% condition is met. The 10% condition is not needed because the eggs were not randomly selected from the population. IncorrectAnswer G
