Please show working. do not use pictures A clinical trial is run to investigate the effectiveness of an experimental drug in reducing preterm delivery to a drug considered standard care and to a placebo. Pregnant women are enrolled and randomly assigned to receive either the experimental drug, the standard drug or a placebo. Women are followed through delivery and classified as delivering preterm (< 37 weeks) or not. The data are shown below.   Preterm Delivery Experimental Drug Standard Drug Placebo Yes 15 23 40 No 83 79 67   Is there a statistically significant difference in the proportions of women delivering preterm among the three treatment groups? Run the test at a 5% level of significance.

Could really use some help with this one please. Thank you. (Highlighted important/useful info)

Please submit the answer via a PDF document or Word document. **Dependent t-test** Use the following data and scenario to answer the questions. A dog trainer is interested in whether the type of environment (park or training facility) will influence how quickly dogs learn a new skill. The dog trainer obtained 40 dogs to participate in the training program. First the 40 dogs learned a new skill at the park and the dog trainer recorded how many hours it took for each dog to learn the new skill. Then the 40 dogs learned a new skill at the training facility and the dog trainer recorded how many hours it took for each dog to learn the new skill. Can we conclude that the type of environment significantly influences how quickly dogs learn a new skill? Alternative Hypothesis: The type of environment significantly influences how quickly dogs learn a new skill. Null Hypothesis: The type of environment will not significantly influence how quickly dogs learn a new skill.   Use the following data…
