In the previous homework, we considered data from four chemical plants that discharged effluents into streams in the vicinity of their locations. to monitor the extent of pollution created by the effluents and to determine whether this differs from plant to plant, the company collected random samples of liquid waste, five specimens from each plant. the data are given in the accompanying table. plant polluting effluents (lb/gal of waste) a 1.65 1.72 1.50 1.37 1.60 b 1.70 1.85 1.46 2.05 1.80 c 1.40 1.75 1.38 1.65 1.55 d 2.10 1.95 1.65 1.88 2.00 we found that there were differences among these plants. in r, use the tukeyhsd function to determine what differences there are among the plants. what plants are different at family-wise error rate (fwer) 0.05

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.

Then it is june the conclusion to the second sentence is just restating "if it is june then it is summer"
