Ten patients with advanced diabetic nephropathy (kidney complications of diabetes) were treated with cap-topril over an 8-week period. Urinary protein was measured before and after drug therapy, with results lis-ted in Table 1 in both raw and In (natural log) scales.Table 1: Changes in urinary protein (in g/24 hr) after treatment with captoprilRaw ScaleIn ScalePatientBefore AfterBefore After125.610.13.242.31217.05.72.831.74316.05.62.771.72410.43.42.341.2258.26.52.101.8767.90.72.07 -0.3675.86.11.761.8185.44.71.691.5595.12.01.630.69104.72.91.551.068. What is the appropriate statistical procedure to test whether mean urinary protein has changed overthe 8-week period? 9. Perform the test in Problem 8 using both the raw and In scales, and report a p-value. Are there anyadvantages to using the raw or the In scale?

4. What calculation is used as an absolute estimate of the reliability of a test, taking into account the units of the test, and not being sensitive to between-subject variability?
d) One of the primary end points/outcomes the study listed was the number of days that it took to reach a 50% reduction in symptoms as reported on a 12-Symptom scale. In Table 2, you can see that the statistical test they used to evaluate differences between groups for this end point produced a p-value of 0.97. Please provide an interpretation of this p-value, explaining what it means in terms of whether significant differences exist between the groups in the number of days it took to achieve a 50% reduction in symptoms on the 12-Symptom scale.
Also need to find the standardized test statistic, decide whether to reject or fail to reject, and interpret the decision in the context of the claim.
I. Background The Food and Drug Administration (FDA) tries to find out whether there is a relation between the number of years people smoked and the percentage of lung damage. FDA asks you for your help to find it out. You interviewed twenty people who have smoked and obtained the following data. II. Technical report: d) Choose your own significance level a (1 suggests 0.1, 0.05 or 0.01). State and test the hypothesis. Explain what your findings mean. e) Do your observations in part (b) agree to the results from part (c) and (d)? Explain f) Find the regression line equation. Explain what the line implies. g) Draw the regression line on your scatter plot. h) A man has smoked 13 years. predict the percentage for damage on his lung. (( please check images for accuracy, thank you!!!))

The mean annual salary of (public) classroom teachers is $55.4 thousand. A hypothesis test is to be performed to decide whether the mean annual salary of classroom teachers in Ohio is greater than the national mean. What is the classification of the hypothesis test?
What is the test statistic? What is the p-value? Can we conclude that the mean travel times of the two routes are different? Yes or No?
Suppose that Dietitians recently recommended a 400 cal per meal and take her children of the age of the data set. To see if both groups adhere to the guideline follow the steps to develop and test a statistical hypothesis. Test to see if us groups means are different from 400 calories. You have two data sets so you'll be completing the process twice. Use 0.05 as a level of significance and make sure to report any important statistic with your results (e.g., mean of each group, standard deviation of each group, test stastistic (are you using t or z?), rejection region and p value). 1. Draw the rejection region 2. determine if the test static falls within the region of rejection or non-rejection.
