Find the equation of the regression line, and explain the meaning of its slope. b. Plot the data points and the regression line. c. Explain in practical terms the meaning of the slope of the regression line. d. Based on the trend of the regression line, what do you predict as the life expectancy of a child born in 2019? e. Based on the trend of the regression line, what do you predict as the life expectancy of a child born in 1580?2300Mr. James McWhinney, president of Daniel-James Financial Services, believesthere is a relationship between the number of client contacts and the dollar amountof sales. To document this assertion, Mr. McWhinney gathered the following sampleinformation. The x column indicates the number of client contacts last month andthe y column shows the value of sales ($ thousands) last month for each clientsampled a. Determine the regression equation.b. Determine the estimated sales if 40 contacts are madeThe personnel director of a large hospital is interested in determining the relationship (if any) between an employee’s age and the number of sick days the employee takes per year.

- The following ordered pairs provide data about some Nestlé snacks, where the first number is grams of sugar and the second is the number of calories for each snack. (3, 110), (14, 180), (13, 150), (11, 120), (8, 100), (5, 70), (7, 140), (15, 200), (12, 130) a. Construct a scatter plot of the data. Does a clear linear relationship exist between the two variables? b. Estimate the regression equation and identify the value of the slope. c. Which conclusion can you draw from your results?The heights above sea level and average winter temperatures of cities in a particular country are collected. The summary statistics for this data are as follows: Sea level: AVG = 5400 ft, SD = 2100 ftAverage winter temperatures: AVG = 40 degrees F, SD = 25 degrees Fr = -0.7 If a city is 5000 ft above sea level, what is its predicted average winter temperature, using the regression line to make the prediction? Choose the answer that is closest. Group of answer choices 50 degrees F 45 degrees F 35 degrees F 40 degrees FA random sample of ten professional athletes produced the following data where x is the number of endorsements the player has and y is the amount of money made (in millions of dollars). x y x y 0 2 5 12 3 8 4 9 2 7 3 9 1 3 0 3 5 13 4 10 Draw a scatter plot of the data. Use regression to find the equation for the line of best fit. Draw the line of best fit on the scatter plot. What is the slope of the line of best fit? What does it represent?
