A primary health center health center reported that in a sample of 400 patients 80 had severe fever. The director of health has asked you to compute a 90% confidence interval for the population proportion with severe fever. Compute the required confidence interval. Your answer should follow the logical sequence as done in class. Incidentally the 95% confidence interval is (0.1608, 0.2392). Explain why the 95% confidence interval will be larger than the 90% confidence interval. The Director went and...

A National Center for Health Statistics study states that the height of adult women in the U.S. is approximately normally distributed with a mean ? = 63. 8 inches, and with a standard deviation of ? = 2.8 inches. Amy is 70 inches tall. Determine the probability that a randomly selected woman in the U.S. is taller than Amy. Would this be unusual? Illustrate by noting relevant details on the normal curve below (label the x axis!), and shading the...

A random sample of 124 women over the age of 15 found that 3.68% of them have been divorced. A random sample of 290 men over the age of 15 found that 5.86% have been divorced. Assuming normality and using a 95% significance level, test the claim that the proportion of divorced women is different than the proportion of divorced men. For this scenario, provide a hypothesis test with all six steps and provide both the critical value and the...

Epidemiology Question: The diabetes follow-up study included 218 diabetic women and 3,823 nondiabetic women. By the end of the study, 72 of the diabetic women and 511 of the nondiabetic women had died. The diabetic women were observed for a total of 1,862 person years; the nondiabetic women were observed for a total of 36,653 person years. Calculate the incidence rates of death for the diabetic and non-diabetic women.

A sample of 30 houses that were sold in the last year was taken. The value of the house (Y) was estimated. The independent variables included in the analysis were the number of rooms (X1), the size of the lot (X2), the number of bathrooms (X3), and a dummy variable (X4), which equals 0 if the house does not have a garage and equals 1 otherwise. The following results were obtained: Coefficients Standard Error Intercept 15,232.5 8,462.5 X1 2,178.4 778.0...

We have a sample of 9254 participants, 4557 men and 4697 women. The mean age of the sample is 34.33 years; men mean age is 34.12 (Variance= 663.063). The Variance in the women's group is 637.5625. Can you calculate women mean age? If so, is there a statistically significant difference between men and women mean age?
