Study Purpose: The aim of this randomized controlled trial was to compare a nursepractitioner lead intervention to standard prescription of controlled-releaseoxycodone for patients who had undergone cesarean section. Participants werefollowed to explore their experience of pain and how pain impacts maternal healthover three months.Post-intervention pain scores were measured using a pain scale ranging from 0 (nopain) to 10 (maximum pain). The results for this study are summarized in the tablebelow.Table 2.

Dr. Wiese wants to determine whether duration of pregnancy and type of opiate use among pregnant women predict developmental delays in their children. In a sample of 30 new mothers, Dr. Wiese measured the duration of their pregnancies (premature, mature, postmature) and the type of opiate that they used during pregnancy (oxycodone, heroin). All participants' babies were then rated on how closely they have met developmental milestones on a scale ranging from 1-10. 1. What is an interaction effect? Use the above scenario if it helps you explain it. 2. What does "two-way" refer to in the Two-Way ANOVA? 3. Identify one of the independent variables. How many levels does this variable have?
A clinical trial is planned to compare an experimental medication designed to lower blood pressure to a placebo. Before starting the trial, a pilot study is conducted involving seven participants. The objective of the study is to assess how systolic blood pressure changes over time untreated. Systolic blood pressures are measured at baseline and again 4 weeks later, in mm Hg. Is there a statistically significant difference in blood pressures over time? Run the test at a 5% level of significance. PLEASE SHOW THE ANSWER IN EXCEL FORMAT WITH FORMULAS.
In the population of senior students at Shermer High School, the proportion who plan to attend college is 0.64. In a random sample of 100 students from this population, the proportion who plan to attend college is 0.75. We would call the value 0.64 a P-value. z-score. parameter statistic significance level.

Look at the ANOVA table. These are the results of an experiment that was done to test whether C (soil carbon) would differ after various methods of site prepartation before tree seedlings were planted. To measure carbon in the soil, the 0-5 cm and 6-10 cm topsoil depths were sampled and analyzed for C. Thus, there were 2 depths, 3 treatments sampled about 26 years after site prepartation occured. a. How do we test the significance of ANOVA? b. One of the assumptions of ANOVA is that the variance of Y is the same for all x values (Xi). What is meant by that statement?

A survey was conducted two years ago asking college students their top motivations for using a credit card. You think the distribution has changed. You randomly select 425 college students and ask each one what the top motivation is for using a credit card. Can you conclude that there has been a change in the distribution? Use a=0.10. 1. Determine the critical value, and the rejection region. 2. Calculate the test statistic.
Significant again? A new reading program may reducethe number of elementary school students who readbelow grade level. The company that developed thisprogram supplied materials and teacher training for alarge-scale test involving nearly 8500 children in severaldifferent school districts. Statistical analysis of the resultsshowed that the percentage of students who did not meetthe grade-level goal was reduced from 15.9% to 15.1%.The hypothesis that the new reading program producedno improvement was rejected with a P-value of 0.023.a) Explain what the P-value means in this context.b) Even though this reading method has been shown tobe significantly better, why might you not recommendthat your local school adopt it?
