4. 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 Experimental Drug Standard Drug Preterm Delivery Placebo Yes 17 23 35 No 83 77 65 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

The Journal of American Medical Association published a study that examined a sample of pregnancies that resulted in the birth of twins. Births were classified as preterm with intervention (induced labor or cesarean), preterm without such procedures, or term or post term. Researchers also classified the pregnancies by the level of prenatal care the mother received (inadequate, adequate or intensive.) The data is summarized below. Figures are in thousands of births. Is there evidence of an association between the durations of the pregnancy and the level of care received by the mother?

A group of disabled women ages 65 and older were followed for several years. It was found that those who had a vitamin B12 deficiency were twice as likely to suffer from severe depressions than those who did not.a. Describe the type of study being performed.b. Describe the explanatory variable(s) and response variable(s).
3. A research study was conducted to examine the efficacy of a new chemical for soil stabilization. Soil samples were randomly assigned to one of three groups: a group that received a low concentration, a that received a moderate concentration, and a group that received a high concentration of the stabilizing chemical. After four weeks of treatment, the samples were tested. The higher the score, the more stable soil sample. The data and ANOVA table for the test are presented below. Complete the group table and also test whether the chemical is effective. Low dose Moderate dose High dose 38 22 14 47 19 26 39 8. 11 25 23 18 42 31 5 Source SS df MS F Between Error Total
Researchers Regine Dilla and associates wanted to determine whether consumption of cola is associated with lower bone mineral density. They looked at 1125 men and 1413 women in the Framingham Osteoporosis Study, which is a cohort that began in 1971. The first examination in this study began between 1971 and 1975, with participants returning for an examination every 4 years. Based on results of questionnaires, the researchers were able to determine cola consumption on a weekly basis. Analysis of the results indicated that women who consumed at least one cola per day (on average) had a bone mineral density that was significantly lower at the femoral neck than those who consumed less than one cola per day. The researchers did not find this relation in men. (a)Why is this a cohort study? (b)What is the response variable in this study? What is the explanatory variable? (c)Is the response variable qualitative or quantitative?
As a hospital administrator of a large hospital, you are concerned with the absenteeism among nurses aides. The issue has been raised by registered nurses, who feel they often have to perform work normally done by their aides. To get the facts, absenteeism data were gathered for the last three weeks, which is considered a representative period for future conditions. After taking random samples of 64 personnel files each day, the following data were produced. Because your assessment of absenteeism is likely to come under careful scrutiny, you would like a type I error of only 1%. You want to be sure to identify any instances of unusual absences. If some are present you will have to explore them on behalf of the registered nurses. a) Design a P chart. The upper control limit is blank and the lower control limit is blank. (Enter your responses rounded to three decimal places. If your answer for the lower control limit is negative, enter this value as 0.)
A scientist is studying the effect of a new type of exercise program on cardiovascular health. The scientist randomly assigns individuals to either the exercise program or a control group. The scientist wants to determine if the exercise program has a statistically significant effect on cardiovascular health. The scientist monitors cardiovascular health by measuring the blood pressure of each individual.
In a study of 301 Hispanic women living in San Antonia, Texas, one variable of interest was the percentage of subjects with impaired fasting glucose (IFG). IFG refers to a metabolic stage intermediate between normal glucose homeostasis and diabetes. In the study, 24 women were classified in the IFG stage. The article cites population estimates for IFG among Hispanic women in Texas as 6.3%. Is there sufficient evidence to indicate the population of Hispanic women in San Antonio has a prevalence of IFG higher than 6.3%? Use 95% confidence level and the p -value method to form your conclusion. The computed z score was 1.193. Find the p-value.
