отполн =) Question 1 - bare another: - perform a mann-vachitmay ustest on the following data: Sample 1 = [2.7, 2.1, 4. 6, 3.8, 5.9] Sample 2 = [ 19.2, 4.6, 21.4, 5.9] what is the rank Sum of sample 1 ? Rank sum (the answer should be an integer) depend on one use statistical table: Mann- whitney u distribution alz)=0.05 alz)= 0.01 what is the Rank Sum for Sample 2? (the answer should be an integer 3 what is the u-statistic= (the answer should be an integer) U₁=1,1₂ + 2₁ (^₁ + 1) - R₁ z U₂ = 1₁7₂-4₁ what is the le-statistic for sample 2? (the answer should be an integer) The hypothesis of the test are: Ho: Sample 1 and sample 2 were drawn from populations with the same medians. HA Sample and sample 2 were drawn from populations with different medians LASSume that the two populations have the same shape) For the above set set up what is the critical value of the u Statistic Lorresponding to a significance level of 0.05? tthe answer should be an integ The hypotheses of rest are: Ho: Sample 2 sample 2 were drawn from populations with the same medians (Assume that the two populations he the same shape) that is the outcome of the test? Do not reject null For 3 sample siz Retect the null at sig leve I 0.01 one canot draw any conclusions about the hypotheses Reject will at sig level 0-= Ponplusions about medians can be drawn only if the pop are normally distribu with a mean of
