Dataset physical is available here. The figure for this exercise is a scatterplot of y 61 60 Head circumference (cm) gཆ ཆུ 56 55 54 59- 58 57 = head circumference (centimeters) versus x = height (inches) for 30 females. 53 60 62 64 66 Height (in.) 68 70 72 (a) Which association does the plot show between the two variables? Explain. There is a positive association since the average head circumference seems to decrease as height increases. There is a negative association since the average head circumference seems to increase as height increases. There is a negative association since the average head circumference seems to decrease as height increases. There is a positive association since the average head circumference seems to increase as height increases. There is no association since the average head circumference is approximately the same across heights. (b) One data point appears to be an outlier. What are the approximate values of height and head circumference for that point? (Round your answers to the nearest whole number.) The approximate value of height is The approximate value of head circumference is in. cm.
