As part of your work for an environmental group, you want to see if the mean amount of waste generated per adult in your community is less than the national average of 5 pounds per day. You take a simple random sample of 21 adults in your community and find that they average 4.3 pounds with a standard deviation of 1.3 pounds. Suppose you know the amount of waste generated per day follows a normal distribution. Test at .05 significance. Round to the fourth H0: (symbol) (symbol) _______ HA: (symbol) (symbol) _______ Test Statistic: P-value: Did something significant happen? (significance happened, nothing significant happened) Select the Decision Rule: (reject the null, accept the null, fail to reject the null) There (is, is not) enough evidence to conclude (the mean amount of waste generated per adult in your community is the national average of 5 pounds per day) (the mean amount of waste generated per adult in your community is less than the national average of 5 pounds per day
