Suppose that a regression equation for the relationship between y = weight (pounds) and x = height (inches) for men aged 18 to 29 years old is expressed with the following formula.Average weight = −250 + 6(Height)(a) Estimate the average weight for men in this age group who are 70 inches tall.lbs(b) What is the slope of the regression line for average weight and height? Complete a sentence that interprets this slope in terms of how much average weight changes when height isincreased by one inch.Average weight increasespounds for each 1-inch increase in height.

Heights and answers to the question, "How much would you like to weigh?" were recorded for n=126 women in a statistics class. A regression equation for y=desired weight (in pounds) and x=height (in inches) is Estimated mean desired weight= - 65.4 + 2.90 (Height) D = bo + bịx a. What is the value of the slope of this regression equation?
The accompanying data are the number of wins and the earned run averages (mean number of earned runs allowed per nine innings pitched) for eight baseball pitchers in a recent season. Find the equation of the regression line. Then construct a scatter plot of the data and draw the regression line. Then use the regression equation to predict the value of y for each of the given x-values, if meaningful. If the x-value is not meaningful to predict the value of y, explain why not.

Based on the analyst's data and regression line, complete the following. For these data, values for earnings per share that are greater than the mean of the values for earnings per share tend to be paired with current stock prices that are (greater than, lesser than) the mean of the current stock prices. According to the regression equation, for an increase of one dollar in earnings per share, there is a corresponding increase of how many dollars in current stock price?
