Unit 4 Chapter 10: Lesson 10.4 Assignment Score: DB 03 answered IQuestionZ - 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. concentration concentration M 31 N on a. M .- I. .- .- .- .- 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 pd = #1 p2, where p1 is the population mean zinc concentration in the bottom of water and pig is the mean zinc concentration in the surface of water. Home Hm b. What is the significance level? c. What is the test statistic? Round to 3 decimal places. d. What is the p -value? Round to 4 decimal places. e. Make a decision. Reject the null Do not reject the null f. What is the conclusion? 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.
