I am a student in my 2nd year of university studying marine biology and doing a retake this Tuesday - sadly none of the answers for the past papers are available and i would like to check I am doing them right as I find statistics quite difficult to get my head around! I've put what i think is correct next to the question in brackets, if i am wrong please correct me and tell me why! Thanks!
a) A one-tailed t-test when P=0.063 for the two tailed T-test (I think this is accept)
b)A kruskall-wallis test when P=0.0036 (I think this is reject)
c)A Mann Whitney test reported as P > 0.05. (I think this is accept)
d)A matched pairs t-test, with calculated t = 3.5, tabulated t = 2.1 at P = 0.05. (I think this is reject)
e)A Kruskal-Wallis test, with calculated value = 11.3 tabulated value = 9.9 at P = 0.05. (I think this is reject)
f) A Z-test reported as P = 0.50, if the decision was based on P = 0.05. (I think this is reject)
g)A Kolmogorov-Smirnov 1-sample test reported with P = 0.325. (I think this is accept)
h)A 1-sample t-test, with calculated t = 7.2 and tabulated t = 2.7 at P = 0.05.(I think this is reject)
i) A matched pairs t-test, with calculated t = 3.5, tabulated t = 2.1 at P = 0.05.(I think this is reject)
j) A Wilcoxon matched pairs test with calculated value = 8.0 and tabulated value = 8.0 at P = 0.05. (I think this is accept)
k) A Mann Whitney reported as P < 0.05. (I think this is reject)
Thanks so much for your help!
