Question 9 To examine the potential effects on the transmission of dengue, Bian et al. (201 mosquitoes from both the WBl (laboratory created) strain and the original wilc dengue. Fourteen days later, the mosquitoes were allowed to feed on an artific for 90 minute. Viral titers in the food solution were then measured in plague fe ml. The results are given below. Mosquitoes were tested in groups, and so eacr average for the group, measured in plaque feeding units per ml. The data have transformed using log(Y+1), to better visualize the differences. WB1: n1 =18 R1 = 35.1 Wild: n2 =12 R2 = 4.5 H0: the distribution of viral titers is the same between the two strains HA: the distribution of viral titers is not equal The data has been ranked from smallest to largest and the rank sum (R1, R2) fOI listed above. Carry out a Mann-Whitney U-test on the WBl data and solve for U decimal place
