Trace metals in drinking water affect the flavor and an unusually high concentration can pose a health hazard. Ten pairs of data were taken measuring zinc concentration in bottom water and surface water of a water source. Zinc Zinc Location concentration in concentration in bottom water surface water 1 .430 .415 2 .266 .238 3 .567 .390 4 .531 .410 .707 .605 6. .716 .609 7 .651 .632 8 .589 .523 9 .469 .411 10 .723 .612 Do the data support that the zinc concentration is less on the surface than the bottom of the water source, at the a = 0.1 level of significance? Note: A normal probability plot of difference in zinc concentration between the bottom and surface of water indicates the population could be normal and a boxplot indicated no outliers. a. Express the null and alternative hypotheses in symbolic form for this claim. Assume la = 41 – 42, where 4, is the population mean zinc concentration in the bottom of water and uz is the mean zinc concentration in the surface of water. Ho: Hā Select an answer Ha:pā Select an answer b. What is the significance level? a = c. What is the test statistic? Round to 3 decimal places. ?v d. What is the p-value? Round to 4 decimal places. e. Make a decision. O Reject the null Do not reject the null f. What is the conclusion? O There is sufficient evidence to support the claim that the zinc concentration is less on the surface than the bottom of the water source. O There is not sufficient evidence to support the claim that the zinc concentration is less on the surface than the bottom of the water source.
