Q9: The data has been ranked from smallest to largest andthe rank sum (R₁, R₂) for each data set are listed above. Carry out a Mann-WhitneyU-test on the WB1 data and solve for U₁.
Answer to one decimal place

Extracted text: The distribution of body size of mosquitoes (as measured by weight) is known to be log- normal (that is, size is normally distributed if log transformed). The log-transformed mean weight of 11 female and 9 male mosquitoes are listed in the table below. Female Male Log-transformed Mean Weight (mg) 16.59 22.96 Standard Deviation 1.8 1.04 Solve for the standard error of the difference between two means. Round your answer to 3 decimal places.
