Looking at the scatterplot what is the maximum value for systolic blood pressure?_150____1 pt. Looking at the scatterplot what is the range of weights for Wt_Grp_3?_. 70__1 pt. True/False. The slope of the regression line is 114.283 and the y-intercept is 0.1128 _true_____1 pt If you plugged the value x = 300 into the regression equation shown on the scatterplot, what would be the numeric result?______2 pt. True/False. According to the trend line where x represents weight and y represents diastolic pressure, a 300lb participant would have diastolic pressure of less than 150. ______1pt. Based on the appearance of the scatterplot would you say weight is a good predictor of blood pressure for this sample? _____ 2 pts. Looking at the Regression Tab, what cell (E.g. E12) in this sheet tells you that weight group 3 does not have a linear relation in terms of weight vs diastolic pressure? _____2 pts

Result:

Looking at the scatterplot what is the maximum value for systolic blood pressure?_150____1 pt.

Looking at the scatterplot what is the range of weights for Wt_Grp_3?_. 70__1 pt.

True/False. The slope of the regression line is 114.283 and the y-intercept is 0.1128 _False_____1 pt

If you plugged the value x = 300 into the regression equation shown on the scatterplot, what would be the numeric result?______2 pt.

114.2828+0.112806*300 =148.1246

True/False. According to the trend line where x represents weight and y represents diastolic pressure, a 300lb participant would have diastolic pressure of less than 150. True 1pt.

Based on the appearance of the scatterplot would you say weight is a good predictor of blood pressure for this sample? False 2 pts.

Looking at the Regression Tab, what cell (E.g. E12) in this sheet tells you that weight group 3 does not have a linear relation in terms of weight vs diastolic pressure? True 2 pts
