1. What are the least, and most, amount of distinct zeroes of a 7th degree polynomial, given that at least one root is a complex number? Answer: If the equation is 7th degree then it has 7 roots. Those roots can be complex or real. Complex roots always come in pairs, so if it has one, then it has 2, the other one being the conjugate of the first one. This in other words, if one complex root is a + bi, then the other complex root is a – bi. If at least one root were complex, then we would have a…

pylori, the CD80 gMFI values of THP-1 cells exposed to H. pylori derived products in the absence of LPS stimulation were determined and compared with the corresponding value of negative controls. Statistical analysis of the values was then performed using one way ANOVA with Tukey’s post-hoc test to find any statistically significant differences between the means of CD80 gMFI values of the negative control, positive control, and test samples. Samples able to activate…

Conversation Analysis (CA) is a concept that emerged between 1964 and 1975 due to research undertaken, and lectures produced, by Harvey Sacks. Despite Sacks’ early death, before he managed to publish his works professionally, we are still aware of his discovery of CA through other sociologists and linguists. An example of this can be seen where Hutchby and Wooffitt (2008) discuss how ‘Sacks originated a radical research programme which was designed to investigate the levels of social order which…

groups (intervention group is 48% and control group is 56%), which means, it is associated with the exposure. 2b. If we perform this unplanned subgroup analysis, the people in smoker subgroup going to have higher risk than non-smoker subgroup, because the confounder may associated with exposure. In addition, because this is an unplanned subgroup analysis, there are unequally distribution between smoker subgroup and non-smoker subgroup, and study not randomize. Two statistical issues will be…
