Water scarcity has traditionally been a major concern in the Canary Islands. Water rights are divided into shares, which are privately owned. The article "The Social Construction of Scarcity. The Case of Water in Tenerife (Canary Islands)" (F. Aguilera-Klink, E. Perez- Moriana, and J. Sanchez-Garcia, Ecological Economics, 2000:233-245) discusses the extent to which many of the shares are concentrated among a few owners. The following table presents the number of owners who own various numbers of shares. (There were 15 owners who owned 50 shares or more; these are omitted.) Note that it is possīble to own a fractional number of shares; for example, the interval 2 3 contains 112 individuals who owned at least 2 but less than 3 shares. Number of Shares Number of Owners 18 1-<2 165 2-<3 112 3-<4 87 4<5 43 5-< 10 10-< 15 117 51 15-< 20 32 20-< 25 10 25-< 30 30-< 50 Construct a histogram for these data. Approximate the median mumber of shares owned by finding the point for which the areas on either side are equal. Ь. Approximate the first quartile of the number of shares owned by finding the point for which 25% of the area is to the left. C. d. Approximate the third quartile of the number of shares owned by finding the point for which 75% of the area is to the left.

Transcribed Image Text:Water scarcity has traditionally been a major concern in the Canary Islands. Water rights are
divided into shares, which are privately owned. The article "The Social Construction of
Scarcity. The Case of Water in Tenerife (Canary Islands)" (F. Aguilera-Klink, E. Perez-
Moriana, and J. Sanchez-Garcia, Ecological Economics, 2000:233-245) discusses the
extent to which many of the shares are concentrated among a few owners. The following
table presents the number of owners who own various numbers of shares. (There were 15
owners who owned 50 shares or more; these are omitted.) Note that it is possīble to own a
fractional number of shares; for example, the interval 2 3 contains 112 individuals who
owned at least 2 but less than 3 shares.
