Confidence Interval for Hemoglobin Large samples of women and men are obtained, and the hemoglobin level is measured in each subject. Here is the 95% confidence interval for the difference between the two population means, where the measures from women correspond to population 1 and the measures from men correspond to population 2: − 1.76 g/dL < μ1, − μ2< −1.62 g/dL.
a. What does the confidence interval suggest about equality of the
b. Write a brief statement that interprets that confidence interval.
c. Express the confidence interval with measures from men being population 1 and measures from women being population 2.

- Find the equation of the regression line for the following data set. x 1 2 3 y 0 3 4arrow_forwardAnswerarrow_forwardA U.S. Food Survey showed that Americans routinely eat beef in their diet. Suppose that in a study of 49 consumers in Illinois and 64 consumers in Texas the following results were obtained from two samples regarding average yearly beef consumption: Illinois Texas = 49 = 64 = 54.1lb = 60.4lb S1 = 7.0 S2 = 8.0 What is the appropriate Test statistic? Name it and Compute its value.arrow_forward
- Suppose we have a sample of ten values of hemoglobin Alc (HgbAlc) obtained from a single diabetic patient. HgbAlc is a serum measure often used to monitor compliance among diabetic patients. The values are 8.5%, 9.3%, 7.9%, 9.2%, 8.8%, 9.1%, 9.3%, 9.9%, 9.7%, and 10.3%. (a) Estimate the population mean, u. (b) Solve for the standard error of the mean. You can use the MS Excel(WPS sheets or Google Sheets) for the computation of sample standard deviation. (c) Construct the confidence interval at two standard error away from the mean.arrow_forwardWhat would you set your alpha-level at? Adrian examined the calcium intake in three groups of individuals with varying levels of bone mineral density. Group 1 had low bone mineral density, Group 2 had moderate levels of bone mineral density and Group 3 had high levels of bone mineral density. In order to determine the mean differences between the groups on calcium intake what statistical test would be best used in this scenario? Why?arrow_forward
