Affected?/Type Pine Fir Cedar Total Yes 59 33 53 145 No 180 129 125 434 Total 239 162 178 579 The table shows a recent random sample of different tree species and whether or not they have been affected by a drought. At a 10% Level of Significance, test to see if whether a tree is affected by the drought is dependent on species. 1. The hypotheses are : O Ho:Trees species and drought effect are dependent Ha:Trees species and drought effect are independent O Ho:Trees species and drought effect are independent Ha:Trees species and drought effect are dependent 2. This is a O twoO rightO left tailed test; d.f. = 3a. The STS (to 2 decimals) is x = 3b. The P-value (to 3 decimals) = 4a. The decision at a = 10% is ODo not reject Ho
