Reseаrchers аre studying twо different designs оf cоmputer keyboаrds, J and K, to investigate to effectiveness of the design on the speed of data entry.  The researchers believe there is a tendency for people entering data with keyboard J to have faster entry times compared with people entering data with keyboard K.  Using the same setof data for entry, the researchers randomly assigned 5 people to keyboard J and 6 people to keyboard K and recorded the number of seconds each person took to enter the data.  The following dotplots show the observed entry times for the two keyboards.    a) Explain why it is not appropriate to conduct a two-sample t-test for the difference in population means. b) Based on the dotplots, explain why it might be more appropriate to compare population medians instead of population means. One test used to compare population medians is the Wilcoxon Rank Sum Test.  Under the assumption that the shape and variability of the distributions are the same, the test uses the rankings of the combined observed values.  To conduct the test, the entry times for keyboards J and K are combined into one group and then ranked from 1 to nT, the total number of observed values in the combined group.  The observed entry times, in seconds, for both keyboard types are shown in the following table.    c) Consider the observed entry times for keyboards J and K. (i) Complete the following table to assign ranks to the observed entry times for keyboards J and K combined. (ii) Use the completed table in (i) to calculate the sum of the ranks assigned to each keyboard. Sum of ranks for J (SRJ): Sum of ranks for K (SRK): The hypotheses for the Wilcoxon Rank Sum Test are as follows. H0:  The median of the distribution of entry times for all users of keyboard J and the median of the distribution of entry times for all users of keyboard K are the same. HA:  The median of the distribution of entry times for all users of keyboard J is less than the median of the distribution of entry times for all users of keyboard K. The test statistic W for the test is
