1. Is gender associated with a person's environmental awareness? Two hundred randomly selected individuals were surveyed about their environmental awareness. Participants were asked about recycling, use of aerosol sprays, and various other environmental concerns. A point system was developed to score the individuals' responses. Once the points were tallied, individuals were broken up into categories of environmental awareness. Those with scores of 8 to 10 were considered to be very environmentally aware, scores of 4 to 6 moderately aware, and 3 or less not aware. The results are shown in the following table:
