Health and nutrition researchers have studied the possible association between family income and the height of children in the family at various growth stages. Suppose numbers from a recent study of five families showed the following results:

Annual Family Income ($000)                     Height of 10-year-old Male Child (inches)

56.4……………………………………………………………………         46.1

22.7……………………………………………………………………         43.6

34.9……………………………………………………………………         44.3

72.3……………………………………………………………………         46.0

58.2……………………………………………………………………         46.5

Show the scatter diagram for the data. Compute and interpret the covariance.
