-Identify why you choose to perform the statistical test (Sign test, Wilcoxon test, Kruskal-Wallis test). -Identify the null hypothesis, Ho, and the alternative hypothesis, Ha. -Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. -Find the critical value(s) and identify the rejection region(s). -Find the appropriate standardized test statistic. If convenient, use technology. -Decide whether to reject or fail to reject the null hypothesis. -Interpret the decision in the context of the original claim. A weight-lifting coach claims that...

Using the Kruskal-Wallis Test, test each claim. Please show work and or chart so i understand how to do it! Exercise 7. Births by week day. A researcher knows that there are more births during the week than on the weekend. The researcher wants to know if the distribution for the number of births is the same for the five week days. The data gathered are shown in the table below. At α = 0.05, can you conclude that the...

Four different paints are advertised to have the same drying times. Use the Kruskal Wallis Test – Analysis of Variance by Ranks, to verify the manufacturer’s claim. Remember that seven samples were tested for each of the paints. The time in minutes until the paint was dry enough for a second coat to be applied was recorded. Below are the results. Paint 1 Rank Paint 2 Rank Paint 3 Rank Paint 4 Rank 114 112 126 115 117 118...
