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.

DYouTube O Mastering Biology .. Find the value of the sample F statistic. (Use 3 decimal places.) What are the degrees of freedom? (numerator) (denominator) (c) Find the P-value of the sample test statistic. O P-value > 0.100 O 0.050 < P-value < 0.100 O 0.025 < P-valuc < 0.050 O 0.010 < -value < 0.025 O 0.001 < P-value < 0.010 O P-value < 0.001 (d) Based on your answers in parts (a) to (c), will you rejecl or fail to reject the null hypothesis? O Since the P-value is greater than the level of significance at a = 0.05, we do not reject Ho. O Since the P-value is less than ör equal to the level of significance at a - 0.05, we reject Mo O Since the p-value is greater than the level of significance at a = 0.05, we reject lg. O Since the p-valuc is less than or equal to the level of significance at a - 0.05, we do not rejert Hg (e) Interpret your conclusion in the context of the appication. O At the 5% level of significance there is insufticient evidence to condude that the mearis are not al.éoual. O At the 5% level of significance there Is sutticient evider ce to conclude that the mcans are not all egual. O At the 5% level of significance there is insufticient evidence lo condlude that the nicans are al equal.
