kaplan-meier survival curve
The AssignmentUsing Week 8 Dataset (SPSS document) from the Learning Resources area, answer the following:DataCreate a variable for Time-to-event by subtracting the start time (variable = start) from the stop time (variable = stop). Label the new variable “Time”.Produce the appropriate descriptive statistics, numerical and graphical, for the following variables:EventIntervalTxNumSizeTimeKaplan-Meier Survival Analysis (Without factor or Strata)Run a Kaplan-Meier analysis in SPSS, using Time as the Time variable and Event as the Status variable (Be sure to define the event). Do not add a factor or strata at this time.Produce a Survival Table (you do not need to submit this)Produce a plot of the survival functionWhat is the mean survival time (include confidence intervals)? What is the median survival time (include confidence intervals)? Why do you think they are so different from each other?Kaplan-Meier Survival Analysis (With Factor)Run a Kaplan-Meier analysis in SPSS, using Time as the Time variable and Event as the Status variable (Be sure to define the event). Add Tx as the factor.Test the difference between Tx groups (Compare Factor) using Log-Rank, Breslow, and Tarone-WareProduce a plot of the survival functionDescribe what the Overall Comparisons mean in terms of treatment groups and survival times.Kaplan-Meier Survival Analysis (With Strata)Run a Kaplan-Meier analysis in SPSS, using Time as the Time variable and Event as the Status variable (Be sure to define the event).

1. Find the y-intercept of the equation of the regression line for the following data:
Please round to the nearest thousandth. Consumer Price Index 30.2 48.3 112.3 162.2 191.9 197.8 Cost of Pizza 0.15 0.35 1.00 1.25 1.75 2.00 2. Find the slope of the equation of the regression line for the following data:Please give your answers rounded to the nearest hundredth.. Consumer Price Index 30.2 48.3 112.3 162.2 191.9 197.8 Cost of Pizza 0.15 0.35 1.00 1.25 1.75 2.00 3.For a certain set of data, the Pearson correlation coefficient was 0.87. It was calculated based on 50 data points. Answer the following questions, based off of this information. (a)Let alpha be 0.05. Is the correlation coefficient significant? [ Select ] ["Yes", "No"] (b)Using your answer from (a), is it reasonable to fit the regression line to the data? [ Select ] ["Yes", "No"] (c)If you were to the predict a value of the dependent variable, would you use the regression line or the mean of all the values of the dependent variable? [ Select ] ["Regression line, or "Mean of all the values of the dependent variable"] 4. 4. For a certain set of data, the Pearson correlation coefficient was -0.467. It was calculated based on 8 data points. Answer the following questions, based off of this information. (a) Let alpha be 0.05. Is the correlation coefficient significant? [ Select ] ["Yes", or "No", "", ""] (b) Using your answer from (a), is it reasonable to fit the regression line to the data? [ Select ] ["Yes", or "No"] (a)If you were to the predict a value of the dependent variable, would you use the regression line or the mean of all the values of the dependent variable? [ Select ] ["Regression Line", or "Mean of all of the values of the dependent variable"] 5. In a study conducted by University of Arizona researchers, the total weight (in pounds) of garbage discarded in one week and the household size were recorded for 62 households. The linear correlation coefficient is r = 0.759 and the regression equation is = 0.445 + 0.119x, where x represents the total weight of discarded garbage. The mean of the 62 garbage weights is 27.4 pounds and the 62 households have a mean size of 3.71 people. What is the best predicted number of people in a household that discards 50 pounds of garbage? Round to the nearest hundredth6. A sample of 40 women is obtained, and their heights (in inches) and pulse rates (in beats per minutes) are measured. The linear correlation coefficient is 0.202 and the equation of the regression line is = 18.2 + 0.920x, where x represents height (based on data from the National Health Examination Survey). The mean of the 40 heights is 63.2 in. and the mean of the 40 pulse rates is 76.3 beats per minute. Find the best predicted pulse rate of a woman who is 70 inches tall. Please round to the nearest tenth.
