please answer the following:

Question 5 0.5 pts A study investigated how the content of vitamin A in carrots is affected by the time being cooked. In this example: 0 X represents the amount of time, in minutes, that the carrot slices were cooked 0 Y represents the content of vitamin A (in milligrams) in the carrot slices The least-squares regression equation for this relationship is: Y = 21.4 0.75X What is the slope of the regression line? Provide a numeric value as shown in the equation. Question 6 0.5 pts A study investigated how the content of vitamin A in carrots is affected by the time being cooked. In this example: a X represents the amount of time, in minutes, that the carrot slices were cooked 0 Y represents the content of vitamin A (in milligrams) in the carrot slices The least-squares regression equation for this relationship is: Y = 22.4 0.65X What is the slope of the regression line? Provide a numeric value as shown in the equation. Question 7 0.5 pts At a large state university, the Statistics department is interested in tracking the progress of its students from entry until graduation. In this example: a X represents a student's nal numeric grade {out of 100) in an introductory statistics course a Y represents a student's nal numeric grade (out of 100) in an upperlevel statistics course The least-squares regression equation for this relationship is: Y = 5.70 + 0.91X What is the slope of the regression line? Provide a numeric value as shown in the equation. D Question 13 At a large state university, the Statistics department is interested in tracking the progress of its students from entry until graduation. In this example: 0 X represents a student's nal numeric grade (out of 100) in an introductory statistics course 0 Y represents a student's nal numeric grade (out of 100) in an upper-level statistics course The least-squa res regression equation for this relationship is: Y = 5.20 + 0.93X Using the regression equation, for a student who received an 85 in the introductory statistics course, predict the student's numeric grade (out of 100) in the upper-level statistics course. Provide your answer as a numeric value rounded to two decimal places
