The quantity of dissolved oxygen is a measure of water pollution in lakes, rivers, and streams, Water samples wgie Laken at four ditterent locations in a river in an effort lo determine if water pollution varied from location to location. Location I was 500 meters above an industrial plant water discherye po nt and neat the shore, I ocation Il was 200 meters above the discharge point and in midstream. Location III was 50 meters downstream from the discharge polnt and near the shore. Location V was 200 mcters dewnstream from the discharge point and in midetream. The followino table shows the results. Lower dissolved oxygen readings mean more pollution. Because of the difficuity in geling midstreani sarmples, ecology students collecting the data had fower of these samples. Use d 5% level of significance. Do we reject or not reject the claim that the quantity of dissolved oxygen does nútvary trom ong kocation fo another?

The quantity of dissolved oxygen is a measure of water pollution in lakes, rivers, und streams. Water samples weie laken at four different locations in a river in an effurt lo determine if water pollution varled from
location to location. Location I was 500 meters above an industrial plant water discharye po nt and near the shore. Location I1 was 200 meters above ther discharge point and in midstream. Location II was 50
meters downstream from the discharge polnt and near the shore. Location IVwas 200 mcters dewnstream from the discharge point and in midstream. The following tablc shows the results. Lower disolved
oxygen readings mean more pollulion. Because of the difficulty in geLing midstreai sartaples, ecology students collecting the data had fewer of these samples. Use d 5% level of sigrificance. Do we reject or not
reject the claim that the quantity of dissolved oxygen does nútvary From one location to another?
