find the answer

A random sample of 30 married couples were asked to report the height of their spouse and the height of their biological parent of the same gender as their spouse. The output of a regression analysis for predicting spouse height from parent height is shown. Assume that the conditions of the linear regression model are satisfied. What is the slope of the regression line? Choose the statement that is the correct interpretation of the slope in context. EFClick the icon to view regression output. O A. The slope is 0.25. On average, for each 0.25 inches taller a parent is, the spouse is about 1 inch taller, in the sample. i Regression output - X O B. The slope is 0.25. On average, for each inch taller a parent is, the spouse is about 0.25 inches taller, in the sample. O C. The slope is 48.40. On average, for each inch taller a parent is, the spouse is about 0.25 inches taller, in the sample. O D. The slope is 48.40. On average, for each inch taller a parent is, the spouse is about 48.40 inches taller, in the sample. Regression Analysis: Spouse versus Parent The regression equation is spouse = 48.40+0.25 parent Predictor: Constant Predictor: Parent Parameter Estimate: 48.398 Parameter Estimate: 0.247 Standard Error: 39.695 Standard Error: 0.566 T-statistic: 1.219 T-statistic: 0.437 p-value: 0.277 p-value: 0.680 S=7.794899045 R-sq=0.036858791 r=0.1919864344 Print DoneIn a recent poll of 1200 randomly selected adult office workers, 32% said they had worn a Halloween costume to the office at least once. Report the 95% confidence interval for the proportion of all adult office workers who have worn a Halloween costume to the office at least once. Round final calculations to the nearest tenth of a percent. O A. (28.0%, 36.1%) O B. (30.7%, 33.4%) O C. (29.4%, 34.6%) O D. None of these
