The accompanying data are the weights (kg) of poplar trees that were obtained from trees planted in a rich and moist region. The trees were given different treatments identified in the accompanying table. Also shown are partial results from using the Bonferroni test with the sample data. Complete parts (a) through (c). Click the icon to view the data table of the poplar weights and the Bonferroni results. a. Use a 0.10 significance level to test the claim that the different treatments result in the same mean weight. Determine the null and alternative hypotheses. Ho H₁₂: Determine the test statistic. The test statistic is (Round to two decimal places as needed.) Determine the P-value. The P-value is (Round to three decimal places as needed.) What is the conclusion for this hypothesis test at a 0.10 significance level? C O A. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim that the four different treatments yield the same mean poplar weight. OB. Reject…
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. The raw data provided in table below. Does the data suggest that the true average concentration in the bottom water exceeds that of surface water? Use ?=0.01.

Background: Henry Cavendish carried out a series of experiments in 1798 to determine the mean density of the earth, as an indirect means to calculate the gravitational constant. A measurement of 5.5 indicates the earth's density is 5.5 times that of water. 1.Perform the significance test. A.H0: μ=5.513Ha: μ>5.513 B.H0: μ=5.513Ha: μ<5.513 C.H0: μ=5.513Ha: μ≠5.513 D. H0: μ≠5.513Ha: μ=5.513 2.Compute the test statistic. Round your answer to 4 decimal places. 3.Compute the p-value. Round your answer to 4 decimal places.
A researcher interested in the lobster fishery analyzed a population of lobsters living in shallow waters off a cove in Maine. He measured the length of all the lobsters in the population. The data is shown below. Min 11.4 Table 1: Lengths of Maine Lobsters (cm); (N=2,581) Quartile 1 Q2 (Med) 23.4 41.1 Quartile 3 56.8 Max 71.5 What is true of a lobster that is 56.9 cm in length? O It's bigger than all but one of the lobsters in that area About half the lobsters in the area are bigger, and about half are smaller that that lobster It is bigger than about 25% of the lobsters in that area O About 75% of the lobsters are smaller than that lobster
