What is the formula for the median of Grouped data? 

#Section 1: Engineering Mathematics
  1. Median = L + [(n / 2 - cf) / f]* h 
  2. Median = L + [(n / 2 + cf) / f]* h 
  3. Median = L + [(n / 2 - cf) / f] + h 
  4. Median = L* [(n / 2 - cf) / f] * h

Optimisation of a PCR reaction is often a compromise between the competing demands for precision, efficiency and yield. Although the specific effects may vary, generally, increasing the annealing temperature will increase non-specific primer binding and reduce precision. Increasing the length of the elongation phase will reduce the proportion of incomplete newly-synthesised strands and therefore increase yield. In this case, the potential effect on efficiency is unclear. Increasing the elongation phase would increase the reaction time, but the time taken to ramp down to a lower annealing temperature would be reduced.

Following are certain strategies used by pathogen to attack over the host plant that describe plant-pathogen interactions:

                      I                                                                                             II

A. Necrotrophic pathogens                              i) most of the plant tissue remains alive and only minimal cell damage can be observed, as the pathogens feed on substrates provided by their host

B. Biotrophic pathogens                                 ii) In which the host cells are kept alive as described for biotrophic  Pathogens and followed by a necrotrophic stage, in which the pathogens can cause extensive tissue damage

C. Hemibiotrophic pathogens                         iii) attack their host by secreting cell wall–degrading enzymes or toxins, which eventually kill the affected plant cells, leading to extensive tissue maceration. This dead tissue is then colonized by the pathogens and serves as a food source
