Applying the Concepts and SkillsIn Exercises, perform a Kruskal–Wallis test by using either the critical-value approach or the P-value approach.Home Size. The U.S. Census Bureau publishes information on the sizes of housing units in Current Housing Reports. Independent random samples of single-family detached homes (including mobile homes) in the four U.S. regions yielded the following data on square footage. Northeast Midwest South West 3182 2115 1591 1345 2130 2413 1354 694 1781 1639 722 2789 2989 1691 2135 1649 1581 1655 1982 2203 2149 1605 1639 2068 2286 3361 642 1565 1293 2058 1513 1655 At the 10% significance level, do the data provide sufficient evidence to conclude that a difference exists in median square footage of single-family detached homes among the four U.S. regions?

Consider a sample with data values of 57,45,50,39,50,59,60, and 48. Compute the following values a. Mode b. 40th percentile c. Variance d. Standard deviation e. Coefficient of variation

See picture of table attached to answer, thank you Garrison Bay is a small bay in Washington state. A popular recreational activity in the bay is clam  digging. For several years, this harvest has been monitored  and the size distribution  of clams recorded. Data  for lengths and widths of littleneck clams (Protothaca staminea) were recorded by a method of systematic sampling in a study done  by S. Scherba and  V. F. Gallucci"The Application of Systematic Sampling to a Study of lnfaunal Variation in a Soft Substrate  Intertidal  Environment,"  Fishery Bulletin, Vol. 74, pp. 937-948). The data in Tables 8-4 and 8-5 give lengths and widths for 35 littleneck clams. (a)   Use a calculator  to compute the sample mean and sample standard deviation for the lengths and widths. Compute the coefficient of vari­ation for each. (b)   Compute a 95% confidence interval for the population mean length of all Garrison Bay littleneck clams. (c)   How many more littleneck clams would be needed in a…

Listed below are times (in minutes and seconds) that a statistics instructor recorded while riding a bicycle for five laps through each mile of a 3-mile loop. Use a 0.10 significance lev the claim that the samples are from populations with the same median. What do the data suggest? Mile 1 Mile 2 Mile 3 3:18 3:25 3:31 3:14 3:30 3:31 3:15 3:25 3:35 3:20 3:26 3:28 3:16 3:24 3:27 First determine the null and alternative hypotheses. Choose the correct answer below. A. Ho: The samples come from populations with equal medians. H₁: The samples come from populations with medians that are not all equal. D O B. Ho: The samples come from populations with means that are not all equal. H₁: The samples come from populations with equal means. O D. Ho: The samples come from populations with equal means. Compute the test statistic. The test statistic is. (Round to three decimal places as needed.) OC. Ho: The samples come from populations with medians that are not all equal. H₁: The samples come from…
